I mean, what options does Marcus Freeman have in that case?
Hillman was a late offer, so there isn't exactly a lot of time to adjust. Not to mention, Hillman was a backup plan due to Bowen wavering.
Freeman has to believe that his bosses will do something to back him up. Doesn't help to know that ND could have made it work, but chose not to. Meanwhile, Michigan could have made it work and DID. That has to be infuriating if I'm Freeman.
ND is unwilling to give him the necessary tools to hold onto an elite recruit in Bowen, meanwhile, they're not even willing to budge on admissions to get his backup plan.
Thankfully, he at least got 2 safeties, unlike Kelly and receivers in '22, when things were apparent.
It's also very possible that ND's admissions didn't communicate this with Freeman, since it sounds like it was a very late call on not admitting Hillman. This isn't exactly a common scenario. Usually if a kid isn't admitted, this is known prior to them signing their NLI.
