not bad. good kickboxers for sure. But as you said, they can fight in closer quarters because the threat of takedown is not there.

IMO, those fighter are magnitudes between than the IFL, but generally, they are not as established as fighter in the UFC. (But I could be wrong.) Seems to me, the REALLY good kickboxers/thai boxers are in K-1, or have made the transition to the UFC, like Crocop did.
