This fight has "war" written all over it! Soto Karass isn't the biggest puncher at 147 (judging from what I've seen in his last few fights), but he has crazy resolve. Same goes for Maidana at 47, he doesn't have as much power, but he will fight to the death.
Soto Karass will more than likely stand and trade with Maidana (something Alexander didn't do), so this should make for a great fight on the Alvarez/Lopez card. Honestly, I feel like this fight will steal the show.
