I think I have been binging on The Americans way too much lately. Yesterday, while watching NFL playoff games in a bar, two women walked in and I immediately thought that one, with her big, curly hair, was a wig-wearing KGB operative sent to spy on me. I then went to a pay phone and told my informant – in morse code, of course – that the coup was off. Okay, that last part is made up, but I seriously think was a wig.

In college football news, TCU has hired former California head coach Sonny Dykes onto its staff, we name the biggest beneficiaries of underclassmen entering the NFL Draft, and Michigan running backs coach Tyrone Wheatley is reportedly close to leaving the Wolverines staff. Here are some other newsworthy notes in the latest college football news roundup.

New Man in Tuscaloosa – With current athletic director Bill Battle deciding to step down as athletic director, Alabama has hired Arizona athletic director Greg Byrne to be his replacement.

Byrne possesses experience running an athletic department in the SEC, having served as the AD at Mississippi State from 2008-10 before departing for Tucson. Battle, who has been in charge since 2013, has been fighting illness, including undergoing cancer treatment this past summer.

Anchors Up – After a career that saw him be named All-American this past season, Vanderbilt linebacker Zach Cunningham has decided to forgo his senior season and enter the NFL Draft.

Cunningham led the SEC in tackles in 2016 with 125, including 16 for a loss. He is projected to be a first-round pick in most mock drafts.

That Was Quick – It didn’t take long for former UConn head coach Bob Diaco to find a new position, as he was hired by Nebraska to join Mike Riley’s staff as its new defensive coordinator.

“When we began looking for a new defensive coordinator, Bob Diaco quickly rose to the top of the list,” Riley said. “He has coordinated a top-level defense, has proven himself as a great teacher and recruiter, and we are excited to have him join our football program.”
