I reckon Arum would be thinking of the fight on the Floyd/Pac undercard if that happens around Sept/Oct or possibly early 2011.
----------------------------------------------------------- SPOILER ALERT FOR ANYONE WHO HASN'T SEEN THE FIGHT ----------------------------------------------------------- Good wins for both guys. Gamboa demolished Mtagwa inside of two rounds. Rogers was there to be hit all night and Gamboa has frightening KO power for a featherweight (he's probably among the best P4P punchers in the game now). JuanMa took his time early on but once he found his rhythm Luevano had no answers and was finally finished off in the 7th round. A fight between these two would be awesome but I think Gamboa has the more polished skill set and if he fights with a bit of calm (something he never does) he'd batter JuanMa with his superior skills. If he tries to take his head off from round one Lopez has a strong chance to catch him or to wear him down and stop him late.
Replay of JuanMa's fight on Fox on Feb 11th. If you havn't seen either fight and would like to send me a pm and I'll sort you out.
