Chisora has always been slightly underrated It's difficult to estimate his actual level, Fury was the last top contender he faced and it wasn't his fault he was shut off, Fury was on fire that night and the number 2/1 of the division (he put on a WAY better performance than Vitali did, just saying) I think people are considering him finished too soon, i don't think he's far off his peak. Unfortunately for him due to his size he'll always struggle against tall opponents. But lets not forget how not long ago he was the first to knock down Johnson with a single, partially deflected, punch.
