Head coach Greg Schiano confirmed the move Thursday at the NFL Scouting Combine. He said the deal is not official yet, but expects Cooper to sign the necessary paperwork shortly.
Schiano has been trying to complete his staff since he was hired at the end of January. NFL Network insider Jason La Canfora reported that Schiano was blocked from interviewing Arizona's John McNulty and Green Bay's Ben McAdoo for the offensive coordinator position and San Francisco's Ed Donatell for the defensive coordinator position, which were ultimately filled by former Giants quarterbacks coach Mike Sullivan and Ohio State's Bill Sheridan, respectively.
"We're not going to rush," Schiano told NFL.com Thursday at the combine. "The whole time I've said I'd rather be a month late in hiring our staff than a day early. I want to make sure that the chemistry and the fit and the people had the same core values that I do and the same core values that the organization has."
Schiano said that in the past, he felt that it was important to hire a staff quickly, but has since learned better.
"That's not the way to go," he said. "So it's taken maybe longer than I would have liked, but we're going to make sure that the guys that we hired were the right fit."
