News broke Tuesday that Houston Texans star defensive end J.J. Watt may be lost for the season with a back injury, so what does that mean for one of the leagues most dominant defenses? We can quantify Watts bottom-line effect on a game by comparing the Texans expected points added (EPA) per play when he is on the field to their EPA/play when hes not.Since Watts rookie year in 2011, the Texans defense averaged minus-0.06 EPA/play with Watt on the field, and minus-0.04 EPA/play with Watt on the sideline. (Negative EPA is good for defenses.) That difference of 0.02 EPA/play equates to about 1.2 points per game based on Houstons average of 62.4 snaps per game. Those 1.2 points per game would be roughly equivalent to 4 percent win probability each game. So at first glance, Watts absence would be significant, but not necessarily fatal to the Texans playoff hopes.But Watt was not an every-down player in his first year and a half in the league, and his performance found a whole new gear starting in 2013. Since the start of the 2013 season, the difference in defensive performance with Watt on the field and off the field is a whopping 0.09 EPA/play. That equates to 5.6 points per game or roughly 20 percent win probability!There have been only 194 snaps without Watt since 13, so consider the 20 percent win probability number as an extreme upper bound of his impact. That kind of effect on win probability is what might be more typical when a team loses an elite quarterback to injury. But if any single defensive player can have as significant an impact on his teams prospects, it might be Watt, who is both a preeminent run defender and pass-rusher. Wholesale MLB Jerseys China .

Adelaide United coach Guillermo Amor will be forced to watch Saturdays clash against Sydney FC from the grandstand after he was sanctioned by the A-Leagues match review panel for touching a referee.Amor has been issued a one-game touchline ban for grabbing fourth official Adam Fielding by the arm in the 68th minute of Adelaides 3-1 defeat to Perth Glory on Friday night.The incident has also been referred to the A-Leagues disciplinary and ethics committee, who have the power to impose a longer suspension.The usually placid Amor lost his cool when Andy Keogh scored a header to put Perth 2-1 up, despite an apparent foul on Adelaide goalkeeper Eugene Galekovic.There was no malice in the contact but it wwas enough to convince referee Jarred Gillett to give Amor his marching orders.ddddddddddddmor defended his actions after the match, saying he was merely trying to get Fieldings attention.When you dont speak good, some language, normally you use the hands, and the movement.
