Rampy is just way to inconsistent for me to call this. His mental state is suspect as well, rersorting to reckless driving and police chases seems odd behavious to me perosnally. I just think he has progressed form the old days and that Wnady has slowed down a bit.
If Ramp is on his game though I see him winning this in many different ways. Wandy's going to come in a swinging and Rampy's counterpunching has gotten too good for that too work. On the ground Quentin takes it as well.
If Wandy does win I think it will be because Ramspage has developed Glass-chin-itis and will go dwon form a punch, or get dazed from a punch and be set up for knees.
Fail post is fail.
Rampage fights the same as he has always done. Good standup, good wrestling, good takedown defense, good cardio, good chin. Crap at defending leg kicks, does same block with elbows.
Watch Wanderlei's last fight. No coming in swinging. There were about four exchanges, each of which Wanderlei was the reactor not the agressor. The last exchange ended with Jardine get Wanderized 'cos he tried to leg kick Wand (lol at that, worst gameplan ever). Jardine got rocked and Wand didn't let him recover.
Now go watch some other Wand fights and virtually all the time he is the reactor, until he gets them hurt. Doesn't always apply to tomato can fights however.
Rampage had Wanderlei on the ground for a long-ass time (especially in their second fight) and did sweet FA with it. The only time something happened was when Wand went for an armbar in their first fight and when Wand got rocked from a punch and then Rampage followed up with some good G'n'P in their second fight (at end of first ten minute round). Wanderlei doesn't have great BJJ, but he has an excellent defensive guard.
The only thing correct in your post is the last bit, but it isn't because Rampage will have developed a glass chin. It's because Wand's right hits like a freight train and he doesn't let you recover. And the way Rampage covers up when rocked = invite to Muay Thai overdrive beatdown.
Rampage can with this with tko, ko or decision (he has the tools), but I don't fancy his chances.
