Golf. But I think there would be more in individual sports. Can't do team commentary or analysis when teams are in season. Make sense?
I'm with you on the "in season"issue. It just if a UFC fighter/employee is commentating on a UFC event they are never going to be totally honest or impartial. They will sing the company song knowing their "real" job will suffer if they tell the truth.
Could you imagine Miesha actually saying what everyone really thought? "Oh my god! Could Cat Zinganno have been any dumber!" "She prances across the cage, stumbles into Rhonda and simply falls on the floor, while extending her arm for Rhonda to grab." "That fight sucked and if I had paid $60 for the PPV I would demand my money back. What a totally embarrassing display."
