What adjustments should he make? He was seemingly winning the fight until the end so this may almost seem like a moot topic, but one thing I was thinking after rewatching the fight was that maybe he should have gone for the takedown when he had Robbie hurt against the fence. I'm sure when the guy's visibly rocked like that it's hard to switch gears from striking to wrestling, but Robbie seems to have a great ability to stay alive after being rocked, and perhaps taking him down at this point would be the better move. Thoughts?
If he took him down in that moment, and didn't finish him. Without the luxury of hindsight to see that he wasn't gonna finish him standing, either. People would have DEFINITELY questions that strategy. 
How about don't eat robbie punches for 5 rounds
