Why wouldn't they have it? You can call them stall tactics, but if nothing happens to them in the long run, then how is that stalling? By suggesting they're stalling you're insinuating that ultimately something of significance is going to happen to them. I'm confident in saying that's not the case.
Like I said, shady crap happened. I'm quite confident Roy was aware too....but still, legally-speaking, these courses were accredited and were available to all students. Now trust me, I know (and so do UNC fans even though they won't admit it) everything wasn't on the up-and-up and stuff was going on behind the scenes, but I still don't think UNC is necessarily "stalling" as much as they're confident nothing can really be done to them.
Lastly, UNC will laugh at everyone again when this over and think they won. And while that might be partly true, they'll know they got away with it, too. I just feel bad for fans of Duke, UK and other schools who have invested so much wasted time into making it their mission to nail UNC. In the end, I think the joke will be on those people more so than UNC fans. JMO.
