Pacquiao would get destroyed by Edgar and Aldo, but especially Edgar. Edgar is ridiculously fast also, and there's a huge difference between street fight wrestling and wrestling with a guy who was an NCAA Division 1 wrestler. Pacquiao would be on his back before he gets the chance to land a punch. As for Aldo, good luck standing up with him. With a Boxer's base his legs would get kicked from underneath him. He will never have felt the pure power of an Aldo leg-kick, and if Pacquiao tried to close the distance Aldo would just change levels and take him down and submit him. Not taking anything away from Manny as an athlete, but pretty much any Pro Boxer would get mauled in MMA by the top level guys.
