Damn bro, I had no idea you were a big ass heavyweight from your profile pic. We are about the same size, wish I lived closer so I could train with you a bit. 100% honest I gave you round 1 for sure, I gave you round 2 by a small margin and round 3 could have went either way. If you had 30 more secs it looks like you would have finished him but you can't fault the judges for not weighing that attempt heavily as you hadn't really started the submission yet (you were just controlling).
Anyway.. nice work
