Well I think Greenburg made his decision because #1 Recently Wlad has been fighting in Germany a lot and it fucks with the TV schedule and #2 If you're not going to show THE Heavyweight Champion then why bother with the division.

As for Bert Sugar I don't think he's ever had anything good to say about Wladimir

I think Wlad should start to open up earlier and more often, I think the hook off the jab is something that he needs to utilize more (and he will vs Peter as Sam doesn't throw a sharp right cross) and perhaps Wlaqd can put his punches together a bit more, the way he used to do. You know given the state of the division right now and his confidence there aren't too many fighters that would be dangerous for Wlad to fight in his old style....maybe Arreola, maybe Sam Peter, and some others with power or with a solid chin and a good workrate might trouble him but Wlad could go back to fighting in more of a crouch and not really have too much to worry about....and personally I think he should start to mix the two styles (Aggressive and Outside/Safety) during his fights....usually once the first right cross lands his opponents start looking for a way out.
