I’d go with Tank, but I’m biased because I’ve always had a belief that it takes more skill to be a good offensive fighter than a defensive one.
I'd go with Tank because his resume is looking good ATM and he's a bigger guy than Shakur. That being said Shakur was undoubtedly the best SFW in the world, which is something Tank never achieved. If Wahid can get past Martin he needs to target the winner of Loma and Kambosos. But I'd make Lil Shaq next on the list.
I think Stevenson is a better pure technician. That said, Tank does have some genuine craft and refinement to his approach. He's not a crude slugger by any means.
I’ve been saying for a minute that Tank is more skilled than these feather fisted flappers like Haney and Shakur. Those lads are not built for war.
