It appears TH is far too emotional. All the cast off coaches getting gigs at Texas is an example of this. Critical thinkers with a winning edge would look for an actual winner with fresh ideas but alas we are busy reviving the careers of the average to poor coach.
Elite Coaches - X's and O's matched with elite talent, they tend to attract each other. Think Riley and his QB's. They win with young and older players
Average Coaches - These guys preach culture (alignment) and rely on older high talent guys to get wins. Younger players rarely develop until they "learn on the field" or wash out.
Poor Coaches - These guys lose with whoever plays for them. They have a chaotic culture and have no ryhme or reason in their schematics.
TH is average. CS is poor. MB is average. SS is poor. Mackovic was average. I am convinced that Belmont does not want to risk losing face with what may come from rolling the dice and getting an elite coach. Belmont is comfortable with average and can expect a lock down culture which does not rock the boat or risk embarrassment. Belmont is also comfortable with a poor coach as long as he is the "right" guy, see Shaka Smart. Get used to average to below average results, it's the Texas way.
