You never know with Weaver... He was awfully good some nights and others he just would not let his hands go... At their respective bests, Weaver out works him
Tua's best chance would be to catch Weaver early. I think Weaver's heavy hands and bodypunching would let him squeak it out. Weaver also had an underrated jab and I could see him really throwing off Tua's rhythm with it and following it with that right hand.
