i always thought 135 was his max, but he did pretty good at 140. I dont know if he could replicate that against the likes of Progais or Josh Taylor. Gervonta was even small at 135 to me. If he can compete at 140 he will answer my post ,asking if he's one of those special little guys that can dominate and hurt guys much larger than themselves, as Joe Walcott(barbados), Langford, Qawi and Pacquiao were able to do.
