Haney, Lomachenko, Stevenson, Lopez, Taylor, Prograis, Foster and etc. Just cause he beat a green, weight drained fighter doesn't mean much does it? Tank is still a protected fighter.
Loma and Stevenson can both beat him. There are fighters at 140 pounds who can as well, if Tank moves up.
I think at 135 the only people that have a chance are Devin Loma and Shakur. I think Shakur has the best chance. And 140 I do think tank could be beatable because I think his power might not carry up that much and he is much smaller than the guys at 140. Still he has freakish power that is very rare in boxing.
I would like to believe so, but I think he is on the downside. Sharkur seems to be the popular answer.
