Cro Cop has all the groundskills he needs. He's lost ONE fight in his 27 MMA fights (only 4 losses and 2 draws of those) to a submission, and it was against arguably the greatest submission fighter in the game today (Noguiera). Fedor couldn't submit him, or TKO him, neither could Herring, Fujita (twice) or Barnett. This guy has THE greatest takedown defense I've ever seen, and when he DOES hit his back, he's no slouch either. His GnP is pretty damned effective too.

And in all honesty, what threat does he have on the ground in the UFC's heavyweight division?

If CC comes to the UFC, his only competition will be Sylvia. Sylvia's reach and takedown defense are pretty damned good. His boxing is pretty impressive too. I'd give it to CroCop, but I don't think it would be as one sided as everyone thinks. Other than that, he'd DESTROY Monson worse than Big Tim could dream of doing, and AA would be KTFOd early in the first round.

However, I don't think he'll be as effective overall as he was in Pride because of the UFC's cage (which will hurt him on the ground....being pressed up against the fence makes things a bit harder for the guy on the bottom) and the ban on "soccer kicks". However, I think the elbows will help him a lot.

Either way, if he DOES come the UFC, look for him to beat either an Ultimate Fighter slouch (most likely Jardine) or a can of some sort (Eilers, Gonzaga). They won't put him up against their up and coming stars (namely Vera and Kongo) because it can only be bad for the UFC (either an up and coming star or their biggest acquisition ever will lose, but I'm kinda banking on it being the former). Then he'll beat Big Tim, fight AA or Vera, then rematch Sylvia.
