The defense is so good I think it would hurt the 49ers more to lose Davis this season then it would losing Willis. Last season Willis went out for a few games and the defense kept rolling and shitting on opposing offenses like it was nothing, Grant did a hell of a job. When it comes down to it though, P Willis>>>V. Davis. Patrick Willis has damn near already reserved his spot in the Hall of Fame, as dominant as VD is many don't consider him the best player at his position where as Willis is clearly the best LB in the entire league and has been for a while now. In VD's defense though I wonder what kind of damage he would do if he was part of a pass first team. The tight ends considered better then VD(Graham-Brees, Romo-Witten, Gronk-Brady) all have pass first Offenses and QB's who love to throw the ball. All in all both players are straight up beasts. thanks to bitch ass Nolan, Singletary, and McCloughan for actually getting something right and drafting some straight up studs while other teams draft picks turned into 1st round busts.
