To me Adams is the biggest bust. I think the guy's a fraud. The highlight of his career was bambooziling Tomlin into drafting him when he requested and was granted a private meeting with the coach prior to the draft. I don't think he has heart or desire to make the commitment necessary to succeed. He just wants that check and will do as little as possible to "earn it".
Sweed just was 3 bricks shy of a load as they say. Great size and speed, could gain separation better than any receiver on the team. The desire and work ethic seemed to be there. He just had a mental block that he couldn't overcome.
Mendenhall deserves consideration because he was your prototypical Tinman. Except unlike the Tinman, Mendenhall couldn't give a shit that he had no heart. He could have been a very good back in the league for a long time if he had only given a damn.
