You are missing my point. It is not about putting up huge numbers...It is about coming through during clutch times in the playoffs. Evenly matched teams look for that one small window somewhere. Diggs didn't really raise up to that moment during his playoff run with the Bills. It is not about getting 5-catchs and 66 yards per game...he simply couldn't elevate his game to the next level and give the Bills the leverage.
In fact, it is the biggest problem for this team in the playoffs. Every one of your best players need to bring their A-game to the playoffs and be able to gain that small edge that is the difference between victory and defeat.
