"McCoy does not throw the football. McCoy is not the guy holding the ball too long. McCoy is not the guy running into sacks. McCoy is not the guy fumbling."

Just give up, most people whining on here will never understand your logic. 

McCoy has coached top offenses, heck even Dennison has an O in Buffalo that works, they both did this when Siemian has not been the QB.

People speak of coaching "adjustments" like it's a snap I
of the finger. You can't adjust for a QB that holds the ball too long, even on a 3 step drop. Hard to make adjustments when a QB can't beat the SAME D used to constantly confuse and contain him. At a certain point, the player has to make a play.
