If I'm being honest, the Lavar show isn't very good now, but I think it'll get there. Right now, Arrington and Chad Dukes are finding their groove. They're figuring out what works for that show and for the chemistry between the two of them. After they get more comfortable working together and get some confidence in what they're doing, I think it'll be an enjoyable show.
My one piece of advice to Arrington - drop the voices. Sometimes when he goes into a tangent he ends up making these ridiculous voices that do nothing but detract from what he's saying. The sooner he gets away from this, the better.
But if that's the biggest complaint they hear in the first month of the show, they'll be in great shape in the long run. Now, as for the Mike Wise show, that's another story completely ...
