Donahoe picked a total BUST at #5 overall. Despite what is written here, scouting reports at the time were critical of Mike Williams' work ethic. His line coach at Texas even tried to diffuse that by saying Mike was just a "fun loving guy", "had a big sense of humor", but he'd be able to flip a switch once he was in the NFL and work hard to prove himself. It never happened. Williams was a huge kid that was coddled through UT and never learned how to work his nads off. Tom Donahoe and the Bills scouts are 100% to blame for taking Ralph's money and not being able to see through the fun-loving teddy bear good guy image and see that the guy had no drive to become a great NFL player whatsoever.
Donahoe's key failure was the Bledsoe deal though in my mind. He helped division rival New England achieve dynastic status for a player that he only got minimal service for before kicking to the curb and another spin of the QB roulette wheel. They failed to use the leverage they had at the time of the trade to get Bledsoe's contract restructured (bad front office work there) and got rid of the QB that should've been playing while they found a younger viable replacement. I'd like to know if Mort knows something about how the Bledsoe run ended -- one can speculate that Ralph demanded that Bledsoe be cut or rework his deal because of his huge backloaded contract and "doink!" ending to his last campaign. Or, one can guess that Donahoe made the call trusting that his green head coach Mularkey would be able to turn Losman into an NFL QB with a wave of a magic wand or something.
