Also, you could be the 10th fresh person in a row to roll with one of the fighters who is building up for a fight. Subbing him when he's tired and you're fresh is very possible but doesn't mean you're a stud.
Especially considering Matt was getting ready for serra he was probably getting sharked by atleast 3-4 guys.
