We haven’t seen much of Wardley on a high level. But I can see reasons for favoring him over Bruno. He had the type of size, strength, power and durability that leads one to believe he could overwhelm and beat Frank to submission. Bruno had plenty of snap to his punches and a very good left jab . But I’m not sure it would be enough. The green and very limited Bonecrusher Smith managed to get past him
I agree except I don't know if Wardley would have been behind on points, he has better head movent than Frank and is faster, but he would have ate a shed of jabs due to Bruno's long reach and the fact that every time Parker bothered to throw a jab against Wardley it landed, he holds his hands too low and has no guard at all.
Could probably see Wardley pulling it off as he has the power to KO Bruno but I think Bruno was more dynamic than Parker. With Wardley, I need to see how he does against people that can genuinely really punch like AJ, Zhang, Dubois...
Bruno was the better boxer, both can punch, Wardley has the better chin and stamina. Now I'd go for Bruno, in twelve months it might be different.
