Yeh the drug issue is so strange, Tyson admitted he took cocaine and refused to be tested but Hughie hasn't admitted anything but clearly something happened, he was clearly on a ban as he was out for a year while waiting for the drug hearing.
As for his boxing ability he's a beautiful pure boxer and great to watch, has a very good jab and judges distance great on the back foot but always fights the same pace and doesn't go through the gears, that could be his problem he hasn't needed to go to the well as he's had it too easy (besides the end of the Kassi fight where he looked uncomfortable).
I don't rate Parker in the same league as AJ and Tyson (if he comes back) but he's a solid world level guy, obviously has fast hands but nothing else really impresses me. Wins over Takam and Ruiz jr is better then everything Wilder has done let alone Hughie so he's gotta be respected.
I think Hughie will use his height and reach and jab and move to win a clear but competitive fight (8-4'ish). Come on stick your neck on the line what's your prediction?
