I almost think you don't have to hit cleanly against Vinny. I know Bader hits like a truck so it may be a bad example, but he hit Vinny with a half deflected punch and Vinny folded like a bad hand.
Unfortunately for him, all of his flaws in MMA can't just be fixed in training. He could learn better defense, but that's about it.
