Could be a case of Wilder taking his man lightly, but I think it's a little short sighted to talk about how Arreola took him out early so Deontay should have as well. Molina hurt Arreola, got reckless and ran in with his hands down, and got caught with a big counter left hook. In this fight, Molina was a lot more defensively minded and didn't go crazy even when he seemed to hurt Deontay. It's a tough when you're fighting a 240lb guy with big power, who just wants to sit back and have you walk into a counter haymaker.

I think it's pretty clear Deontay needs to diversify his offensive attack and learn to better disguise that big right hand, but to start writing him off because it took 8 rounds to KO a guy is a bit foolish IMO.
