Exclusive of the steroid issue, Merriman's problems started with his reluctance to have surgery. First on his knee and then his Achilles. I understand the reluctance, however when you earn your living as an athlete, when multiple doctors have recommended surgery and time is against you, you either do it or retire. Merriman is lucky to still be in the league, he no longer has the luxtury of time. This is it for him.
That being said I hope he stays healthy, makes the team as a situational player, pass rusher. If he can produce anything near what he once did it makes this defense very tough. You have to root for the guy.
For years I have been saying that the Bills need to start by building a team to beat the Patriots. To beat them you must put preasure on Brady. A healthy Merriman would help.
