So the way that Bo did it allowed both parties to save a little face.
Sadly, this "saving face" concept is why Watson was our OC this year. Change was in the air last year, and he was looking with no results. Rather than fire him, he was kept on with the hopes of improvement this year thanks to consistency. That didn't happen, obviously.
I'm afraid that we'll pull the same stunt this year - we'll let Wats look around, but if he doesn't find something we'll bite the bullet and keep him on. I don't know about Bo, but T.O.'s loyalty to his coaches is legendary.
