no, it was a bad move to keep him more than one year. with a guy like that, you get something and then let go before the cell grows cancerous and starts spreading.
after a year, his self-destruct sequence begins counting down, and it's only a matter of time before he blows the whole place up. cowboys should have done what the pats did with moss: EJECT at first sign of trouble, and while they could still get something for him. but the only team as merciless with their roster as the pats are the eagles, and there's a reason both teams have been so successful over time. sure indy and pittsburgh have been just as successful, but they succeed in part by not taking on problem projects and drafting in part on personality. okay, roethlisburger's had legal problems, and apparently so has marvin harrison, but neither of them f*cked with the team's collective psychology.
