That’s not to say, however, that all trades that fit into this category are busts. The deal that secured quarterback Drew Bledsoe a year ago legitimized the Buffalo Bills, made them immediately competitive, and dramatically moved forward for GM Tom Donahoe a refurbishing of the franchise. There is no player in this year’s draft, none at the No. 14 spot he forfeited to New England, likely to have meant more to the Bills than Bledsoe means to the health of the team.
