The same could be said of Wilder after the 9th round knock down or even the later one, but he couldn't do it. So what makes you think that he would do it to AJ.?
The pundits seem to to think that it was Fury's defence that got him the draw but his attacking ability is a little suspect in that he doesn't attack enough and relies on not getting hit.
That fight just showed that neither will be a match for AJ but the strange things is how can 1 judge give the fight to Fury by 4 rounds and another to Wilder by 4 rounds. At least there was one sensible judge
