David Haye has not even beaten Barrett yet , Lennox Lewis hit Vitali flush on many occasions , are Haye fans saying he hits harder than Lewis ?

Also we have to wait and see how Haye reacts to being hit by a puncher at HW.
At this point Vitali would easily stop Haye , this is based on the fact that he is unproven and Vitali is a known quality.
Haye beating Peter , is another bold statement , you have to remember Peter couldnt get close to Vitali , Peter would be able to hit Haye and again we do not know how he will react.

Im a fan of David Haye but he needs to develope as a HW , less talk more action.
