It's funny how you never hear anyone say, "In that 2004 draft, I know we drafted Wilfork, but I really wanted Ahmad Carrol." Or "I thought Chris Perry was really going to be a late round first round steal in 2004."
Point is, no one pipes up when the player they really wanted turns out to be a bust, and Belichick's (or any other coaches) pick turns out to be a solid player. 31 NFL coaches who do nothing but watch game tape, talk to college coaches, and analyze scouting data for several months consistently make bad choices and draft busts. But know it all arm-chair head coaches need to remind everyone about how right they were 3 years ago when they thought Dunlap was a better play than Cunningham. Frankly, no one cares. There were probably 15 other players you thought were going to be great draft picks that year than never played more than 50 NFL snaps. It's what happens. Stop reminding people of how you, who's probably some fan who probably watched a few of his college games and heard Mel Kiper talk, really were right.
