BARCELONA, Spain -- Four days after affirming its European credentials by toppling Manchester City, Barcelona slumped to a stinging 3-1 loss at Real Sociedad to relinquish the provisional Spanish league lead to Real Madrid on Saturday. Gareth Bale scored a blistering long-range strike to help Madrid brush aside Elche 3-0 at home, and Barcelona was unable to match that with a win. Instead, it was overrun by Sociedads dynamic attack led by forwards Antoine Griezmann and Carlos Vela. Barcelonas defeat confirmed the change in course in the league title race over the past two months, leaving Madrid in command and waiting to see if Atletico can keep up when it visits Osasuna on Sunday. After starting the season with 13 wins and a draw, Barcelona has dropped points in four of its last seven games. Barcelona coach Gerard Martino shuffled his lineup from Tuesdays Champions League victory at City and tried to reinforce his defence by playing with two holding midfielders in Sergio Busquets and Alex Song. The move backfired when Song scored an own goal in the 32nd minute in the first of several defensive lapses that doomed the defending champions. Lionel Messi equalized in the 36th, only for Griezmann to restore the hosts advantage after an error by defender Marc Bartra in the 54th before setting up David Zurutuza in the 59th. The loss left Barcelona three points behind Madrid, the first time it has trailed its fierce rival this season. Atletico is also three points behind Madrid before it plays on Sunday. The last time Barcelona lost by more than one goal was a 3-0 defeat to Bayern Munich in May 2013. Martino took the blame for the humbling defeat. "Real (Sociedad) deserved to win," he said. "I didnt make the correct reading of the game. The decision not to change was also a mistake." Madrid won its third straight game without Cristiano Ronaldo, who was finishing a three-game suspension. Madrid midfielder Asier Illarramendi opened the scoring at the Santiago Bernabeu in the 34th. Bale then squashed Elches timid second-half surge with a blast from about 25 metres in the 72nd before substitute Isco Alarcon sealed the victory in the 81st. Bale was having a discreet outing until his superb strike that hit the underside of the bar and bounced in, securing the three points that made Madrid the overnight pacesetters. "I said My goodness, what a goal when I saw the ball pass by," Madrid fullback Dani Carvajal said. Madrid will visit Schalke 04 on Wednesday in the Champions League final 16 enjoying an unbeaten streak of 26 games in all competitions. Madrid then plays at crosstown rival Atletico next weekend in a highly anticipated league meeting. Also, Celta Vigo fought back for a 1-1 draw at home against 10-man Getafe to leave the visitors winless in the last 10 rounds, while Malaga drew 0-0 at Almeria. Martino was dismissed by the referee during halftime, and Barcelonas first-year manager had to witness the rare sight of his team being thoroughly dismantled from the Anoeta Stadium stands as the festive home fans soaked up their big win. The victory moved Sociedad one point out of fourth place and Spains last Champions League spot as the Basque side deployed its best version of its up-tempo attack to take a good measure of vengeance for Barcelona eliminating it from the Copa del Rey the previous week. Sociedad was unlucky not to widen the final margin when a disheartened Barcelona appeared to tire in the final minutes. Vela almost capped his outstanding performance in the 81st but his shot hit the post. Sociedad went ahead when Gorka Elustondo muscled by Song to meet Sergio Canales cross, which Elustondo appeared to graze with his head before it hit Song in the chest and landed in the net. Messi combined with Martin Montoya to level when Sergio Busquets craftily let Montoyas pass run between his legs for Messi to rifle it inside the upright of Claudio Bravos goal. Sociedad, however, got the winner when Bartra headed Bravos goalkick back toward his own area, where Vela was quick to pounce and crossed for Griezmann to volley in his 15th league goal of the season.

Kadri was dressed in a green jersey at Thursdays practice and skated as an extra forward on the teams fourth line as the Leafs.On the weekend, there were a few things that got me wondering: First, was this piece by Sarah McLellan about Coyotes LW Paul Bissonnette, who is hoping to expand his role beyond part-time fourth-line muscle. Among players with at least 100 minutes of 5-on-5 ice time this season, Bissonnette ranks seventh in points per 60 minutes, which may be a small-sample fluke, but theres a lot of room between Bissonnettes current role and that of a regular in the lineup. The Coyotes have made sure to put Bissonnette in situations where he can succeed, with offensive zone starts and relatively low quality of competition, but hes generated positive possession numbers over the past three seasons, enough to think that he might warrant consideration for more time. Trouble is, with the Coyotes life-and-death to make the playoffs, they dont seem inclined to give him that opportunity right now. The second thing that caught my attention was Flyers tough guy Jay Rosehill scoring a pretty nifty goal against the Bruins. And third, that was against the Bruins, a team that is sort of the prototype for the fighting teams, ranking second in the league with 46 fighting majors this season. The Bruins have Milan Lucic, a first-line winger who fights; Jarome Iginla, a first-line winger who fights; and Shawn Thornton, a fourth-line winger who fights and gets regular ice time (8:32 per game this year and played 22 playoff games last year). Injured D Adam McQuaid and rookie D Kevan Miller are also a couple of tough customers who play third pair minutes for the Bruins. Theres also been a lot of talk this year about Torontos fourth line which, for a time, included both Frazer McLaren and Colton Orr, and the relative ineffectiveness of that fourth line seemed to cause issues higher up the depth chart. Figuring out playing time for a line that employs two enforcers that dont have enough hockey skills to keep up is, at the very least, challenging. Finally, with the playoffs around the corner, the time will come when teams make hard lineup decisions and, in many cases, that means the designated enforcer goes to the press box. If he can play a bit, though, that can tilt the decision. So, all of this wondering led me to try and find out which of the leagues fighters are actually doing enough to warrant regular ice time; basically, who can play? One look at hockeyfights.com provided a list of 75 players that might be considered fighters (there are probably a few more that could have been included), but it was basically every player involved in at least five fights this season, plus a select few that had four and come with a reputation/track record (Steve Ott, Steve Downie, John Scott, Troy Bodie) and then Bissonnette, who has fought only three times in 37 games. There is an obvious top tier, which includes Iginla (with his most fights since 2009-2010), Lucic and Philadelphias Wayne Simmonds, forwards that play on scoring lines, but have an aggressive side that comes out on occasion. They might as well be excluded from the examination because, even with zero fights, they clearly produce enough offensively to play prominent roles on their respective teams. Teams can use tough guys in lower-leverage situations. As Tyler Dellow pointed out a couple of weeks ago, teams can be judicious in their use of their tough guys, which mitigates their liability, but if the tough guys cant play a lick, it makes it increasingly difficult to be judicious. It should be noted that not all fights, and fighters are created equally. There are heavyweights, who tend to only fight other heavyweights; there are agitators who end up fighting because theyre being called to task for one of (likely) many transgressions; and there are players who, battling for a spot in the lineup or consistent playing time, are willing to use that as one more reason for the team to keep them in the lineup. What makes a fighter useful enough to handle a regular fourth-line shift? Players that have at least 47% Corsi is a decent place to start. From a Dellow post last year, he determined averages for first, second, third and fourth-line players. Sure, theres some room for variance, but if the player is going to be used as more than as a spare part, he cant spend all of his shifts scrambling in the defensive zone. Among the 75 listed below, nearly half (36) had a Corsi over 47%. 23 were at 50.0% or better. Players that have at least an even Relative Corsi. From the list below, that includes only 15 of the 75 players, but that makes sense. Fourth-liners are unlikely to have better possession stats than players higher on the depth chart. There are a dozen players that have both a 50% Corsi and at least a break-even relative Corsi (actually, its 10, but Lucic and Iginla are just below that threshold.) If we can take the position that a fighter isnt likely to be the one driving his teams possession numbers, then if they arent significantly worse than their teammates, that at least puts them in consideration for a regular role. There are obvious exceptions to this case too, particularly when it comes to the Bruins, where the Patrice Bergeron line is so dominant that the likes of Gregory Campbell and Shawn Thornton have no hope of being close in terms of relative Corsi. Really, if a player fits in a teams top nine, theres not much question whether hes a useful player. Some are more useful than others, of course, but its not as if the league is overrun by third line forwards that dont even warrant a spot in the league. Maybe this should table should count as an appreciation for Patrick Maroon, the suddenly-valuable winger for the Ducks. While one of the leagues most active fighters, with 13, hes a strong possession player (54.8%) who, like most Ducks, has spent time on the wing with Ryan Getzlaf and Corey Perry, but hes been more productive recently while playing with Mathieu Perreault and Kyle Palmieri. Maroon has 12 points (3 G, 9 A) in his past 15 games, a marked improvement over 17 points in his first 59 career games. Maroons a big guy (6-foot-3, 229 pounds) who paid his dues in the minors, playing 353 AHL games, but hes also been more than merely a puncher, scoring 58 goals and 124 points in 139 games over the previous two AHL seasons. Its been a long road since he was drafted in the sixth round by Philadelphia in 2007, but hes starting to pay dividends for the Ducks. Take what you will from the data below and there is surely some debate over some of these players being on the bubble in terms of value, but when more and more tangible measures are available for players, it becomes increasingly difficult to justify a players spot in the lineup for intangible benefits.
