This report about the U of Miami's offer to Gruden may be interesting, as far as what TN will need to offer:
"These were reportedly Jon Grudens contract demands when he met with Miami AD Kirby Hocutt. 1. A $3.4 million salary 2. A $1 million salary for his brother, Jay, who would be the offensive coordinator 3. A guarantee that if certain winning standards were met Jay would become his successor 4. A private plane at his disposal for recruiting or anything else he wanted. Number three was the problem."
