Cap hits and IR rules aside for a moment, I think there is more to this than we know and the Bills are letting on. As I am getting older, I can say with certainty that the Human body takes longer to heal. If TV has had a nagging injury for several weeks now, and he injured it more in week 1, than I think it is safe to say this may have been a hamstring injury that will hamper him all season long. Moulds had a similar injury one season and he was in and out of the lineup all season. If that were to be the case this season, and the rookie wasn't too bad, then you make this move.
I will reserve judgement on this for a while and see what happens. But I think the wily old codger has made a hard but fair decision....
