It didn't take Duke long to find a new quarterback in this class when four-star Jack Sears (San Clemente, Calif.) flipped to USC last night.

The Blue Devils staff moved fast and pushed for their next guy.

Bowling Green commit Chris Katrenick (Algonquin, Ill./Harry D Jacobs) just committed to Duke, as first-reported by 247Sports.com.

Katrenick said he received a call Sunday from Blue Devils coach David Cutcliffe.

"Coach Cut is the best football mind I've ever met and he told me their situation and how everything happens for a reason," Katrenick said. "He said they were back in the quarterback market and loved me ever since they had me in the summer at camp. He offered me (Sunday and) told me to think about it and get back to them."

Katrenick didn't need long. He informed Duke's staff of his intentions minutes ago.

"My family and I know this is a great opportunity as Duke has elite academics," Katrenick said. "They have great coaches there and I loved it when I went there."

Katrenick chose Duke for many reasons, mainly the academics and his relationship with the staff.

Duke assistant Jim Bridge recruited Katrenick (6-3, 205) for the Blue Devils.

As a senior, Katrenick threw for 25 touchdowns.

The three-star recruit is ranked as the nation's No. 45 pro-style quarterback and the No. 23 prospect in Illinois in the 2017 class by 247SportsComposite.

Katrenick is the 21st verbal commit in the 2017 class for Duke.
