Roger Goodell briefed all 255 members of this year's draft class Monday on the NFL's stricter conduct rules. Hours later, the Bears released troubled Tank Johnson in a move that most likely underscored the commissioner's message. "We're concerned about them as men," Goodell said at the league's rookie symposium in Palm Beach Gardens, Fla., shortly before Johnson's release was announced. "How do they become not only great NFL players, but how do they become great men? How do they conduct themselves appropriately for the remainder of their life, not just when they're in the National Football League?"
