Just what Baltimore needs: another hasbeen WR to complain all season and drop balls in the playoffs.
Yeah, what has Burress ever done in a big game!

Burress was foolish to be carrying the unlicensed weapon in New York City, and
very foolish to be carrying it with a round in the chamber (and without a holster, in his waistband). However, he has paid for this many times over - he suffered a wound; he lost out on a lot of $ in the years he's been behind bars; he did his time in the lockup. If he still has skills at the level he displayed before the incident, he should be picked up by a NFL club. The guy was a game changer for a while.
It all depends on how much his skills have eroded while A). not having pro-level training facilities at his disposal B). spending two years away from his chosen profession and C). if he can convince a NFL franchise that his off-field street-thug persona is a thing of the past.
He'll probably get an incentive-laden contract at veteran minimum as the base, IMO.
