People deserve a second chance, but how about a third or fourth?

Have you heard about Plaxico Burress. He was at a night club and carrying a gun, when it went off and shot himself in the leg. This is not the first time he has done something like this. He has skipped practices and faked injuries. But this brings up a larger problem. Shouldn't athletes know how to act profesionally when they are being paid millions of dollars? All you have to do is get up go to practice or a game and go home you don't need to go clubbing at 2 A.M or have a boat party. Just take advantage of the oppurtunity you have been given.
