Gonna be 💯 % honest, didn't know who Tsyzu was when you posted... Did check out some highlights though and he looks legit (speed and power). Harrison had always been crafty...
I'd go with Tsyzu from there little I've seen

His dad was a world champ fought against Zab Judah and some other big names back in the day. Was supposed to be Tsyzu Charlo but latter got hurt. Harrison will be toughest test for him yet
