I think a lot of you guys are really underestimating the Klitschkos. Yeah, Tyson was probably the greatest puncher in HW history (his combination of power + speed + punching variety is unmatched imo), but like any puncher, he needed to plant his feet.

You guys forget that he often had a lot of problems getting off and landing on big, tall guys who tied him up when he got close. Even 6'4'' bum Mike Jameson effectively tied Mike up and stifled his offense for the first few rounds. 6'4'' James Smith stifled his big punch largely, as did 6'5'' Tony Tucker.

Would Tyson beat the Klitschkos? Like I said, for me it's a toss up. But for all you who think Tyson would just walk in there and bomb them out because they caught punches from Corrie Sanders is just rediculous. The Klitschkos didn't dominate a division just by being big - they have the skill and the knowledge to back it up. They've been great at keep guys out of range and not allowed guys to get set.
