ACC morning links

North Carolina continued its defensive overhaul Monday, hiring former Nebraska defensive coordinator John Papuchis as a defensive assistant. Papuchis becomes the second defensive staff hire for the Tar Heels this offseason, joining former Auburn head coach Gene Chizik, who was hired as the Heels' defensive coordinator, replacing Vic Koenning.

Both assistants come in with notable pedigrees. Both come in with baggage.

Though the Chizik hire was met with some skepticism given that he was accused of NCAA violations during his tenure at Auburn, Papuchis also enters UNC with some questions, given recent events in Chapel Hill.

Papuchis' first employer, Kansas, was placed on probation in 2006 for three years because of violations in its football and men's basketball programs. Among the football team's violations were two transfer players being provided with answers to a test by a former graduate assistant.

Papuchis, who is now on a defensive staff led by Chizik, who in his previous job was investigated by the NCAA for its recruitment of Cam Newton, and who dealt with a number of other accusations, from paying players to changing grades to other recruiting improprieties.

None of those claims stuck with Chizik or Papuchis, but lingering questions remain.

Now they are both working at UNC, which is once again under NCAA investigation for alleged academic fraud in its African and Afro-American Studies classes. Less than three years after being sanctioned by the NCAA.

Coming off one of the worst defensive showings in the country this past season -- and closing the year with a pair of blowout losses in which players openly questioned who wanted to be there -- head coach Larry Fedora was already going to be under heavy scrutiny entering his fourth year with the program. He hasn't made it any easier on himself so far in 2015.
