Adamek is hyped way too much now. What has he done ? Golota is even slower than Valuev these days. The Monte Barrett that David Haye fought was much more dangerous than Golota. As for McCall, this would be a serious test, as McCall can a take a punch much better than Golota. Adamek would have to work for the whole fight, not just for a few rounds. And there off course is the possibility, that McCall can connect with his punches in the later rounds, when Adamek is getting tired and not as fast as in the beginning.
If Adamek fights once in every 2-3 months...why not? It should be a good test against granite chin heavyweight with some power
