I don't think he would school him, Sugar Ray Leonard had some troubles vs Ayub Kalule who was a Southpaw. But the very fact people put Manny Pacquiao, in these fantasy fights vs great Welterweight fighters.
When a few years ago people thought it was suicide, that Manny Pacquiao was moving up above the 10 stone limit. Just shows how great Manny Pacquiao is IMO.
