I'm a big Ando fan, and I think two things about this fight.
One Ando did not look like himself that fight, so I welcome the rematch to see if it is a different case this time (Ando by Murder/death/kill)
Second Chael does not really deserve a immediate rematch, he needs to beat a top contender before getting another shot .
However I will still pay my moneys to watch the fight, so I guess that’s your answer right there.
