I don't get the anst here.
1. He has proven his coaching acumen as a DC
2. He has the perspective and experience of being a P5 head coach
3. He is young, energetic, good-looking, and a great recruiter.
4. He is a dynamite quote machine. This guy will get more "oddball" national attention than Harbaugh (despite what you may think, buzz can be good, especially in recruiting)
*as long as said buzz doesn't include expletive-filled rants about fans and refs
5. He will be a DEFENSIVE COORDINATOR. They are allowed and sometimes encouraged to be quirky, as long as they get results.
6. 3-4 should be fun, let's give it a try.
