John Ruiz Wlad is a very good boxer with good fundamentals. Any criticism of him would be aimed at his attitude and mentality rather than his ability.
That would be ever worse, though. I prefer somebody who tries without any ability over someone with all the ability but a lack of heart.
John Ruiz fought the best of his generation and was ducked by Tyson, Wlad, Quitali and Lewis. Anyone with a win against John Ruiz on their resume deserves alot of credit.
I would describe it as his fear of his own chin, which is not bad as haters would like to think but its not good.
The quiet man. At least Klitschko puts some guys away. Even though he fights like a mouse when fighting less than threatening opponents.
You can appreciate what Wladimir does in the ring if you watch closely at what makes him so effective.
