What exactly were the Pats to do at the point they traded for Sanu? How do we know that they didn't name different terms and ATL simply balked? We needed a WR and they went for one. Too bad he's playing hurt. Unfortunately, that's just where the team was at that point, regardless of who is to blame. Personnel decisions are fluid and there will always be good and bad decisions made.
The problem with threads like this is that the problems, especially in football, can seldom be limited to one player. The offensive problems go far beyond just Sanu or just Meyers or just *insert player name*. The whole unit is off and may not ever be right this season. Whatever improvements the offense can make will likely be only marginal. They simply lack talent and any semblance of continuity or cohesion. We have to maybe accept that it's on the D to make things happen in the critical moments.
