Its a big thing in combat sports to avenge a loss, a lot of fighters never do it or it only happens a long time down the road.
Its a risky prospect because there is always the chance you will go 0-2 against that fighter, not easy to come back after that.
Conor jumped straight back in there and even demanded it at 170 again when he had the option of doing it at 155.
Sorry, but to me that shows he has a fighters mentality, if it was some other fighter people would be praising him non stop for it.
Every one complains about fighters pulling out of fights at short notice and not fighting a replacement, yet heres a gut that took on one of the divisions best wrestler at short notice when aldo pulled out, then starched Aldo in 13 seconds.
Then he jumped up a division to take on the champ RDA ( again people always complain about champs not moving up for superfights, yet conor does it straight away RDA pulls out and conor takes on a diaz brother at short notice at an even higher weight, gets beat and then jumps straight back in afterwards.
