Take what Adamek did to him and multiply that by what Holmes did to tex cobb and add in a little cotto / malignaggi for shits and giggles
Cunningham isn't even very good, never understood the hype he gets. Doesn't have the greatest whiskers either. Marciano K.O at some point in a largely uncompetitive bout.
Its the ultimate result of boxrec warrioring. At some point I think he'd fought everyone who was ranked in the top 5 at cw. He had decent skills but was always far too vulnerable and when adamek left the division he was far too inactive. His win over a green Huck is as good as it'll ever get for him. That being said for a while he was the best guy under 200 as was rocky so a fight is a reasonable ask. However I agree that rocky pushes his **** all the way in.
