Umm... that was OVER FIVE YEARS AGO
... people change you know!
But it is still the ONLY time we have ever seen JDS on the ground for any extended period of time. It's the only thing we have to go off. That and his more recent bout with Carwin, where he was easily swept into a choke at the end of the round.
From the limited amount of time we have actually seen JDS on the ground, he looks to be.....well pretty bad.
