They should have done an all woman's season and an all guys season.
If I was a heavy handed striker getting signed to Rousey's camp, I'd be thinking "What the fk are you gonna teach me?". Rousey is the person you bring in to help out the team with their Judo. She isn't a head coach.
Nick Diaz taps Rousey frequently in training if I remember correctly, so it's not like Rousey is easily the best submission fighter around. I'm sure more than one of these guys would put her out in a Jitz contest.
I'm probably the best at keeping threads on topic of all time.
