I think all 3 fights will be exciting if just for the fighters it will...

I think the fights will in this order of excitement;
Pavlik vs. JT
Kessler vs. Joe
Hatton vs. PBF

I think what makes the Hatton-PBF less credible as far as excitement is PBF's style, when you look at the other 2 fights from the 4 fighters I think JTs the one who would probably be the most cautious.... But I don't think Pavlik will give the room to do so...

So my vote goes to Pavlik-JT.
