Thanks for the support everyone.
Hopefully I'll win by armbar eventually. I just really wanted to test my stand up against someone with touted boxing. I'm sure he was planning on me taking him down and grappling with him, evident by the fact that he shot for a take down right away. I'm sure he had been drilling that a lot. Another reason I wanted to keep it standing, I figured he had been working on his take downs and ground game so I wanted to really time a knee for when he shot it. I just didn't think it would be that soon.
