Serious question: Why hasn't Narduzzi and/or Dantonio been poached to a bigger program?

You have an MSU program playing some consistently elite defense, and doing so at a program not able to attract consistently elite prospects. They've been on a pretty impressive run the past 4 years - 11-2, 11-3, 7-6 (6 losses by a combined 30 points) and now sitting at 7-1 with the top ranked defense in the country. 

Seems to me like Narduzzi should be a prime head coaching candidate at a major conference team, or a DC at a top 10-15 type team and Dantonio could probably be able to climb the ladder to a traditional top 25 type team where he could recruit better and further build his resume. 

I for one hope this happens sooner rather than later. What say you?
