Marco needs to keep his mouthpiece in his mouth. He plays with it too much. I was kind of surprised about how young Marco is. He's still only 22, a few months away from 23. Brandan Wright should get more PT. Maybe because he was sick and missed some games and practices or whatever, that he didn't get in the game sooner. Who knows?
Baron Davis started that last year, where he'd keep it stuck halfway out his mouth, chewing on it like a piece of gum. It's a pretty doofus thing to do, as it's then just dangerous to even use at all. You're just asking to either A) choke on it B) accidentally bite down on your tongue C) have it slip out of your mouth and get distracted while you're playing. Turiaf does it too. It's annoying.
I've play with a mouthpiece for the past 5 years. Let me tell you its saved me at least a couple of trips to the dentist's office. I do tend to play with it a little but not while the play is going on (Turiaf is flat out just playing with it.)
