I don't care how long you've been a season ticket holder. That doesn't mean a damn thing in terms of your knowledge of the game or your knowledge of Belichick both with the Browns and with the Pats.
BB wasn't the GM in Cleveland. He had a say, but not the final say in who was drafted. And, if you actually looked at his record there, he consistently improved that team until the final year when, after starting the season 3-1, it was announced that the Browns were moving to Baltimore. BB was made the sacrificial lamb by the owner, Art Modell.
Brock Williams, Guss Scott, and Tyrone McKenzie suffered major injuries. Are you honestly saying that Belichick should be clairvoyant and know that they were going to suffer those injuries??
David Thomas can hardly be considered a bust. He was a productive special teams player and someone who also missed a year because of an injury.
It sounds to me that you are simply an irrational person who's expectations have little or no foundation in reality.
