Depends on which Parker comes in. The guy climbing of the canvas to beat Zhang probably has too much experience. But there is also the guy who should have a loss do Derrick Chisora. Anyway, I like them both.
I'd slightly favor Parker, but imo it's a bad match up for him as Kabayel can be a very negative fighter.
In terms of provenness there's no comparison - Parker's beaten contenders, whilst Kabayel's best win is one of the worst versions of Chisora I've ever seen... Yet beat a couple of very overhyped fighters and suddenly everyone's huge on him. The fact this poll favours Kabayel says a fair bit about how much this board backs hype over provenness.
