David has the punch and the attitude to make a difference to the HW, however as soon as one of the big guys land a shot on that chin of his it will be good night, David is a great guy and great for the sport, but if he does get in the ring with Klitschko he better make sure he lands the big shot first.

The problem with Heavyweights these days is they are so big, back in the days of Lewis, Ali, etc those guys were more like cruiserweights, they had the punch power but also the movement to make a fight look good, these days you have big plodders like Valuev and then the smaller guys just have to try and work around those long arms. Unless someone with a chin and the power of Tyson comes along again the heavyweights will never be the same again.

The lower divisions will always set up better fights
