Who wins?
Joshua did beat Parker more easily than Wilder beat Ortiz actually.
I highly doubt it, Chavez was as close to unknockoutable as anyone's ever been in his prime.
Whitaker, Mayweather, Chavez, Ross and Cervantes all have a fair chance IMO.
Saunders shut O'Sullivan out, how's that struggling with him?
A little but as others have said, i think his best days are (already) behind him.
