Carwin is on a 2-fight losing streak, hasn't fought in 14 months, and is 37 years old coming off a serious injury.
Roy Nelson is 2-3 in his last five fights, is fat enough to be a natural middleweight, and is 36 years old.
Like I said, IRRELEVANT
A good match up is a good match, regardless of records and places in divisions. So tired of seeing MMA fans spout off about irrelevance. Its all about the fight.
