It is legitimate. Mario did not buy into Rex's scheme. He admittedly did not drop in coverage when the plays called for it. He was the 93rd rated pass rusher in the NFL. 93rd!?!! He had, I believe 16 or 18 tackles all season! There is film on him where he absolutely did not engage with the offensive tackle. Bills players called him out all year. More importantly, it was more symbolic that the Bills did not have the right players or the buy in necessary to Rex's 4-6, or 3-4 under, or 5-2, whatever you want to call it. This year Rex brought in Ed Reed and his brother to fix the communication and discipline issues. The defense appears to have bought all in, and although we lost Marcel to suspension and it it is a big factor, the Bills defense has gained some back in continuity what it lost in talent. Anyone who thinks chemistry and continuity is not a factor in football is fooling themselves. With this and Tyrod showing improvement, the Bills fans have something to latch onto no matter what the national media thinks. This will not be an easy game. The first team, although they didn't play much, dominated the line of scrimmage against the Colts and Giants on both sides of the ball. Good Luck on Sunday. May your team come out clean without any injuries.
