I will preface by saying I'm an OU Alumni and happened to see Blake Griffin for the 2 years he was here and there's no questioning this guys talent.
I will admit that we haven't seen what he can do, or if he can do it consistently against many of the leagues top forwards. But judging by some preseason performances I think it's safe to say he can hold his own.
If he stays healthy, i think you will be eating your words
Pau, Lamar, Kaman, all good players no doubt but none of them are guys you build a team around. Griffin just might be..
