Peterson had the better win, beat the better fighter. Kirkland had the more interesting and compelling performance.
I think Kirkland's was a better win for his confidence than Peterson's. I think Peterson's win is better for his career though.. He can rematch Khan and if he wins he'd get huge props.. Or he can move to Bradley or someone else at 140 since he's the title holder.. Not sure who wants to fight Kirkland..
KOing someone in their backyard isn't harder than doing it in your own Peterson's win was way bigger, lets be real here
