I think Pulev fights similar to Vitali at times, at least did earlier in his career, his jab and stance are similar and he leans back a lot like Vitali used to.
I would actually have to say Jack Johnson. He seems to methodically break his opponents down though it almost looks like he is toying with them. He actually enjoy putting the hurt on his opponents like a bully.
This is an absolute joke. Froch has nowhere near the skills of Vitali. He is a poor mans Vitali, there is no argument.
