I would only accept this fight as a five rounder. That said, I think Condit would get his first submission in 6 years over Brown.
Brown has definitely strengthened his ground game over the last few years, but it's still a liability, and Condit has fought nothing but tremendous grapplers for a while.
That said: Even on the feet, I think Condit could finish the fight with his pace, volume, and body shots.
