Considering how far his stock fell in the first fight with Karass he certainly managed to do some good damage limitation at least yesterday.

I'm still not sold on him against a world rated opponent but he definitely showed he can learn and adapt and boxed a fine showing yesterday.

I'm not convinced that Karass, for all his heart however is anything more than a gatekeeper, and beating him convincingly in a rematch isn't a whole lot more than when Chavez Jr had to refight Matt Vanda.
