DURHAM - N.C. State football coach Tom O'Brien and his staff observed Duke's spring practice on Monday morning.
Duke coach David Cutcliffe said that since the teams do not face each other for the next three seasons (in 2013) that they could welcome in the State staff.
"It's not often that you get to watch another team's practice," Cutcliffe said. "So we agreed to swap out a day to watch each other work. That's really all it was, end of story."
Cutcliffe, who enters his third season at Duke, said his staff will attend an N.C. State practice when they start this spring.
