One guy is way younger than the other
One guy has a very high punch output as opposed to the limited punch output by the other guy
The older guy will need his legs to win the fight
The old guy is a master of fighting dirty
The young guy is undefeated
The young guy will be facing his toughest fight
One is black the other is white
The old guys have never been this much of an underdog before
Pretty interesting I think.
