Im sure you wrote in another thread that he gave you the best reach around youve ever had. So maybe you can inform Boxrec.
An exception doesn't make the rule. Reach is a good advantage, but a guy with a short one should always try to find a style that suits him... which is what Tyson did better than anyone but not everybody is Tyson. Povetkin's reach would be a hell of a disavantage against a Klitschko.
