Saw some confusion about whether the Tuf fights actually counted towards their records or whether they were exhibitions that don't count, and I think I have the answer.
The first round of fights were just 2 rounders, and thus exhibitions that didn't count toward their record. The next round was upgraded to 3 rounders and thus those count towards their record.
Noticed this when I saw that cuccinello is still undefeated, while some of the earlier guys have a loss on their record.
