I have no problem giving Boston a shot. Correct me if I'm wrong, but he's never played in a West Coast Offense, has he? He's a perfect possession receiver - experienced enough to get open, big enough to go across the middle and take a hit (and keep on going). He could be everything that Ferguson is supposed to be.
And speaking of Ferguson, any move that increases the chance of him playing for another team next year is a good move to me.
The difference between Boston and T.O. is that Boston will be cheap. Minimal investment, and a decent chance for a big return on that investment. If he stinks it up, or becomes a distraction in the locker room, cut him.
