I like Klitschko,and am not a huge fan of Floyd(his mouth not his skills)
With Floyd asking him to go toe to toe,is to A) Ask him to toss his biggest asset,and B)Ask him to not fight like a typical Welterweight
Asking Klitschko to get in there and mix it up is asking him to A) USE his biggest asset,his power and B) Fight like a typical heavyweight

Vitali's much better at keeping busy,and look at his KO ratio
There really needs to be a SuperHeavy division,so people know to expect these 2 punch at a time fights
