FILE - In this Sept. 10, 2016, file photo, Baylor offensive coordinator Kendal Briles, right, watches players warm up before an NCAA college football game against SMU in Waco, Texas. Coach Willie Taggart drew some scrutiny for hiring Briles, who worked for his father, Art, at Baylor as that school went through a bruising scandal tied to sexual assault accusations. He will have to work around a deficient offensive line, but if the offense clicks then Taggart’s second year in Tallahassee should be much better than his first. (AP Photo/LM Otero, File)

FILE - In this Saturday, April 14, 2018 file photo, Alabama quarterbacks coach Dan Enos talks with quarterbacks Kyle Edwards (16) and Mac Jones (10) before the NCAA college football team's indoor scrimmage in Tuscaloosa, Ala. New coach Manny Diaz calls luring Enos from Alabama the most important transfer he landed this offseason. Few teams have been so shackled by poor quarterback play the past couple seasons. If Enos can turn either N’Kosi Perry, Tate Martell or Jarren Williams into an above-average QB, the Hurricanes’ first year under former defensive coordinator Diaz could be a memorable one.

FILE - In this Saturday, April 13, 2019 file photo, Michigan offensive coordinator Josh Gattis during the team's annual spring NCAA college football game in Ann Arbor, Mich. Gattis is perhaps the most intriguing new offensive coordinator in the country as Jim Harbaugh seems to be ceding control in favor of a more modern approach. It’s not as if the Wolverines weren’t running spread elements and run-pass options last season with quarterback Shea Patterson. But bringing in Gattis suggests a more immersive approach.(AP Photo/Carlos Osorio, File)

FILE - In this Saturday, Oct. 25, 2014 file photo, Michigan defensive coordinator Greg Mattison walks the sidelines during the second half of an NCAA college football game against Michigan State in East Lansing, Mich. New Buckeyes coach Ryan Day swiped Mattison from Michigan. One of the most respected defensive coaches in the country, the 69-year-old Mattison now joins forces with the 40-year-old Hafley to remake a defense that was maybe the worst in school history last year. Scheme tweaks include the use of a promising defensive back Shaun Wade in a safety/linebacker hybrid role. (AP Photo/Carlos Osorio, File)
