I actually think it would be a good hire and here's why:
1. Manny understands that we need schemes (offense and defense) that fit our local talent base. He probably understands this better than any candidate out there. This is a main reason why the last two coaches failed. Golden with his horribly passive defense and Richt with his plodding non explosive 30 year old offense. Bad fits for our local talent.
2. He's not stubborn. The guy adjusts. In fact, he's one of the best I've seen at it. He adjusts in game, but he has also demonstrated that he is willing to self scout and adjust his scheme. Remember last year when we would be torched in the base 4-3 but would flourish in nickel? The guy went and implemented the striker position as a result and the defense got even better this year. He would identify weaknesses on the team and address them.
3. He understands that you can't just line up and beat the other team with talent. There was an article with quotes from Diaz where he said exactly this. I don't have the link, but in that article he stated that you have to scheme advantages for your guys wherever you can. Tilt the odds in your guys favor. Reading that was music to my ears. That's the name of the game in 2018 and beyond.
4. Combining #1 and #3 above, is there any doubt that Manny would go out and hire an innovative light up the scoreboard oc? I have no doubt that he would.
5. He's young and hungry.
6. He'll be aggressive. No more taking a knee before half or being afraid to run up the score. He would be pedal to the metal.
