Ok who else is there then? Fury, Wilder, Price? Hardly greats themselves. You can only fight who is around at the time. Now, unless you can get yourself a DeLorean and put the date back to the 1970s-1990's, then his legacy will hold up.
He's already a great heavyweight, nobody dominates as long as he has without being a great, it's undeniable. Where he ranks as an ATG of course is up for debate. He's just outside the top 10 for me. Whether or not he breaks into the top 10 will depend upon how long he continues to dominate for and also what happens after he retires. Fact is he has nobody on his resume that could be regarded as an ATG. But there is always a possibility he beats someone at the tail end of his career who goes on to be dominant and be regarded as great. If he were to beat Joshua and Fury and one of them go onto the be the dominant heavyweight champion it has to add to Wlad's legacy.
That is the paradox that many cannot comprehend when they make the "Not great until you beat a great" bollox statement.
An excellent post and a thoroughly enjoyable read. I have Wlad in the 12-15 atg heavyweights range and that is despite his reign being littlered with defences against what many would consider sub standard opposition. Its not his fault though is it? He never ducked anyone. There simply wasn't sufficient genuine world class heavyweights. I also consider Wlads success to elevate Stewards trainer ranking. That is two heavyweights, which were at the crossroads of their career when ES took over their training, and both end up in the top 15 atg HWs and one of them (Lewis) is comfortably a top 5 atg HWs. That is a fantastic achievement no matter which way you look at it.
