The UFC is paying Hendo alot of money and need to promote him, he lost his 1st 2 UFC fights and then beat a fighter who is not known to casual fans. Making Hendo the coach makes alot of sense IMO. Bisping is obviously a no-brainer to coach the UK team.
I don't see Bisping beating Leban though, so who knows. If he does, Hendo is going to give him the beating of his life.
