I think this is a good thread topic and agree with original poster.
This is one thing about the "THUG" identity. In many cases the guys that are the thugs are also STUPID. Tank Johnson wasn't truly a thug, but he did some dumb things, seemed to have a dumb attitude last year, and didn't step up his play. Now PacMan was a thug and anybody who squanders that much talent and that much existing and potential money is also not intelligent. Terrel Owens is clearly not a thug. He never is in trouble with the law, BUT he might just keep himself out of the hall of fame if he isn't careful. Has he hurt his career by being "dumb" with his constant selfishness and personality clashes, sure he has. He has hurt his teams in as many ways as he has helped them.
Irvin was a bit of a thug. Same with Eric Williams, but somehow they had the street smarts and caring/winning personalities to get it done on the field too. Their co-players would be willing to sacrifice for these guys (although at the end, Irvin was pushing it too) but after a while I ain't gonna kill myself for a "I love me some me" teammate, sorry.
Gregg Ellis is another example of a guy that just doesn't strike me as all that bright all the time. Nice guy, who doesn't realize he doesn't do himself any favors by acting like a victim (woe is me, they drafted another linebacker, I have competition - woe is me they didn't extend my contract or redo my contract and pay me extra millions I don't deserve because I haven't lead this team to anything yet, etc). These type of guys just don't step up in the big games.
Even Crayton needs to be careful. He talks a bit too much and then boom he drops a key ball in the playoffs and looks like he cuts a TD potential pass route a bit short. Woopsy, the world likes to attack the big mouth that didn't come through.
Intelligence and street smarts in football players is an underrated skill. A number of players have made great careers without having the same physical talent, but by having a large dose of those intangibles, intelligence included. Ask a Zach Thomas or a Dat Nguyen or a Dexter Coakley, or a Steve Largent, etc.
