Agreed. In Dirrell's two ''major'' fights he's fluffed it mentally. Ran all night against Froch and took the easy way out against Abraham. Since then he's done absolutely nothing.
Kessler is via split Dirrell is an athelete not a fighter as we saw in the later rounds Vs Abraham. Kessler while a bit robotic at times is miles better than Abrham - if Kessler lands with any consitancy Dirrell will look for the shortcuts and loose, just like he did with Froch and the headbut and just like he did with AA
