Yeah I can't imagine the argument for Hartman leaving. Bolt early, hope nothing goes wrong and you crush it in the combine to avoid going undrafted? And that's your best-case scenario?
Or stay at Wake as a walking deity, you get Perry, Williams, Greene, and Morin as your receivers. You get Ellison/Cooley/Turner in the backfield. Some losses on defense but I still think we'll be better defensively next year, whether by personnel, getting healthy, or scheme.
Plus unlike this year it won't be UNC getting all the pre-season hype. We'll be the defending Atlantic champions, Howell will be gone and Hartman will get some light chatter about the Heisman... We get the two teams we lost to at home. You have to assume not all of those pieces will fall thanks to the portal and all the bad advice out there, but even selfishly another great year while he's not flying under the radar would do wonders for his draft potential.
