I'ts difficult to write him off at this stage because he is not even in great shape. If he works on his conditioning he should be ok.
I don't give him as much flak for his performance as for his conditioning and his general physical shape. It's not his skills that are lacking, it's his attitude towards the sport and his chosen profession.
Atlas was what was wrong. Atlas tried to make him a power puncher....before Atlas Povetkin was superbly conditioned combo machine. Didn't need power, with that volume of accurate fast hands. And fast hands are powerful in their own way.
