Yeah I don't know...Conor has a history in boxing, is more of a stand up fighter, doesn't have an insane ground game, has really only usually lost when it came to the ground, etc. Plus Floyd insisted on the 10oz gloves, though he's fought at 8oz forever...he's afraid of how much power Conor has perhaps...

And let's not forget the tale of the tape.

Shorter, reach disadvantage. Sure it's Floyd's world but for anyone instantly thinking it's his fight...be careful lol.
