You can armbar anyone if you can get their arm straight. So in Ronnie's case, yes if the situation is right.
But, give Ronnie 10 minutes of training and tell him not to straighten the arm, and I doubt too many guys in the world will armbar him.
Heel hook, fine. Choke, fine. I'd just run circles around him for a minute and when he gases, toss him to the floor.
