"A successful coach?!?!"
As is usual for NU, this is not just any gig. It's a difficult needle to thread. And if you want to keep him long term and not go through this exercise every three years, I think you need to think big ... beyond the money and length.
First of all, I hope Jackson and CC have enough of a relationship that they can have a heart to heart. "Do you REALLY want to stay?? Or do you not think you can do what you need to do here?"
If he says he wants X years or to find a place where he can get to the Final 8 as often as NU gets to a tournament, then it's a different conversation.
But if he and his wife are TRULY dedicated to making this work, I think he needs some help beyond salary. A strong salary and contract length is just the start. but I don't know how any D1 coach can work at the portal-era pace for 10+ years. Some programs have "GMs." I'm never sure what that means, but I think of it as an agent/coach for the program. Maybe two guys?
Also, if you're thinking about a 7-10 year plan, Jackson needs to start thinking about whether the next guy is a CC guy.
Any kind of construction promises? Increased salaries for the assistants.
I think the discussion become one of:
a) "What can this be?"
b) Investment and infrastructure
