We've had some players come here and make us think that we found gold only to fall of the earth after a year. Note: I started following the Patriots during Bledsoe's rookie year (I was 14) so there is probably someone deserving of this title that is well before my time. My vote goes to Tyrone Poole. I remember Pasquarelli had him ranked #1 among sleeper free agents that season. He was lights out all year in 2003. He led the league in pass deflections and was as good if not better than Ty Law. They threw at him as much as they could because of Law on the other side and he handled it. He even did well when Law missed time. All this after so many wanted to cut him because of his second thoughts about leaving his family to come here. Then he turned to crap after that. Injuries and just overall drop in play turned him into a liability rapidly.
