I never thought of an 8th time division world champion would be an underdog. It seems OP has no good analysis when it comes to a match like this. An experience one vs. a new one in this league would overpower the old one.

Maybe, if he thinks that Manny is so old enough for a fight but I do not think coach Roach would allow Manny to fight if Manny is capable.of bringing down an opponent.
