So, you don't see improvement from when Briles took over to where Baylor is now?
Sure I see improvement, so what? Improvement doesn't = better coaching. If it did, then Nick Saban isn't really very good since his teams haven't really improved much in the last few years. It would have been harder for Art Briles NOT to improve he started at the bottom.
The post you quoted stated that on paper, Art Briles isn't a better head coach than Bo. I think that's true. Your counter was that he has a better record than Bo this season, and then your next point to me was that he has improved the team. Those are two elements out of literally dozens that factor into being a good coach, and only about half of them are able to be documented (not even getting into the discussion about being ethical, clean and honest). Bo has had better recruiting classes every year, has three divisional titles compared to none for Briles, owns head-to-head over Briles, better winning percentage, more consistent product on the field, better graduation rate, etc.
So again, I don't know what point you're trying to make.
