I completely disagree,he showed in the klitschko fight he had the tools to hang in the division just not the desire.
In the Klitschko fight it showed he was way too small he had to be negative as he was too small to get his range, I don't see what else he could have done in that fight. He would have just got knocked out had he been more aggresive. Klitschko's are masters at keeping a fight at range, that's the reason why fighters like Holyfield and Toney have avoided them.
he didn't take much damage in that fight,he could certainly of been much more positive imo he got into range ea
