Drop him
Edit: This is the only reason I didn't put T.O. up very high when I went to the draft board. I felt it was just as safe to go with a reciever like Marvin Harrison, Hines Ward or Chad Johnson, while only Harrison hasn't had any contract issues, they're still going to pay off because they'll stay on a team throughout the season.
T.O. is a high risk, high reward player. I prefer the mediocre players at WR and draft high at the RB spot.
