Watching the highlight videos I see a pretty versatile defender too. On occasion we come across a team with a very big point guard. It’s hard for Tavari and Young to hold off 6-5, 6-6 players from getting a head of steam. Marvin and this guy look to have the lateral quickness and size to make life difficult for them.
Edit: Even though we haven’t seen Eric Mahaffey, I imagine he will be able to help guard these big point guards as well.
