Whoever the opponent in sept the fact is if aj steamrolls him he probably won't get much credit as said opponent will be deemed past it, paid off, hopefully he gets a Few rounds under his belt but I guess even then the haters will say it's worrying he couldn't ko him within 2 rounds
I would go for a boxer that could last longer than a couple of rounds and actually test him. I'd go for Tiger Thompson, that would show how far he's gone.
