BJ Penn vs Floyd Mayweather?

5 rounds in mma, i have 2 go with floyd mayweather jr for multiple reasons, 1st bieng that frankie edgar (i dont agree with his victory, i think penn got robbed) did out box penn using angles and rotating on his heal side 2 side and in and out, whose better at using angles than floyd, 2nd, floyd prides himself on his hard work conditionong and athletisim, im not saying that whatever bj is doing with marv moranivitch isnt working but floyd brings phisical conditioning to a hole new level, last and im sure the thing thats on everyones mind is the ground game, im not stupid, i no that bj would floyd if it hit the floor, but there are two variables to consider before you think about the mat, one is obvisouly floyds hand speed and punching power in 4oz gloves, it would be otherworldly, but lets say bjs chin holds up, the second variable, would bjs pride allow him to take it to the ground, it seems to me that bj covets being known as one of the best boxers in mma and i think that he would want to try and beat floyd at his own game, this is my opinion, i considerd all things win coming up with this, im eager to hear of what all you guys think, intellegent posts please, not jus " bj would win cuz he would take him down" or " floyd would win by knocking him out"
