You could but your name dropping fighters who aren't anywhere near current top Heavyweights, if he does face the likes of Whyte and upwards the 2 big factors are that he's not a big Puncher even at Cruiser and can he take a punch from a full blown "live" Heavyweight.?
That remains to be seen.
I honestly think even someone like Bellew could walk right through him at Heayweight.
His speed will get him right in the mix no question but then he's gotta go into the trenches at some point.
