Jake has some shitty wrestling but it is probably enough to take Nick down I think. He has some overwhelming top control when he isn't as drained as he was fighting at welterweight. Nick won't be able to submit him ( I think Jake has the better BJJ out of the two ). Probably enough for a decision victory for Jake.
I think Nick can stay standing enough to do damage and eventually get a finish with his hands. I don't think either one would sub the other. Nick has a crazy pace and Jake's standup is shit.
