TS, your bias is showing.
I like Cain. He earned and deserves to hold that title again. But there's nothing flukey about a punch from JDS. Some people act like getting punched behind the ear means it's not fair play. Besides, having a good chin is generally is understood as the ability to take a punch period, not just square on the front portion of the jaw. And if you're still reaching, then come up with something to explain the GnP that actually put him away.
Cain doesn't need your excuses. He got his belt back with a vengeance. Stop making Cain fans look bad.
He's lost to one guy in the UFC, and that's JDS. And vice-versa for JDS losing only to Cain. These guys are phenomenal. Who's to say how a 3rd fight will look between them? They're 50/50, and finish or not, both won pretty damn convincingly. Writing off the proven ability for JDS to knock people out is kind of silly. That's a very real threat.
How about let's be excited these two are at the top of the division, and now we have Cormier in the mix and possibly some other Strikeforce names crossing over. When Jones eventually fills out and moves up in the next couple of years, HW is going to be more exciting than it has ever been in UFC history.
