P Wee wins with his Jab and defence. Pacquiao wouldn't get 'clowned' though and would win rounds himself with activity. 8-4 or 7-5 Sweet Pea.
If you think Pac is limited enough to only have a 4 year period where he was on the top of his game that's on you. Maybe I rate him higher than you. The reality is Pac was a different beast at different weights because he had to be. Sfw and below he could overwhelm with physicality. From LW and above he would overwhelm with speed. Different approaches.
If Eric Morales and Juan Marquez could outbox Manny then I can’t see why Sweet Pea couldn’t. Whittaker is bigger and better than those two. I realise he is a southpaw unlike the two I mentioned but I feel that Pea’s hand and foot speed, jab, ability on the inside and all round trickyness would enable him to outpoint Pac-Man. Cheers All.
