Samuel Peter is the most exciting heavyweight in my judgement, however, he could improve on certain critical aspects of his style; you are correct. Wladimir Klitschko is a classy fighter and individual. How many times does one see a fighter with an earned PhD (with dissertation) in the professional ring? Well, his brother, I guess. They are both family men, articulate and gentlemanly; that speaks for well the division too. One cannot avoid noticing Nikoloai Valuev at 7", 223 lbs. He is currently 44-0; he is educated, soft-spoken and has a devastating uppercut (ask Etienne and Beck). Finally, young Notre Dame football standout, and captain, a true scholar-athlete, Tommy Zbikowski, has quite a following and some strength and skills as demonstrated at MSG last Saturday night; if he came down to cruiserweight, he would have a fine boxing career.
All in all, the heavyweight division is most interesting and promising. If one is only interested in truculent fighters, watch Valuev, I sense he is getting a little mean!
