No one knows except a select few as you point out. Apparently Drinkwitz is the flavor of the day from some media sources as I have a friend texting me the merits of his resume. I would be surprised about Hartline being the leading candidate. I think Kraft wants a sitting HC unless his top choices all pass.For what it's worth, Hackenberg said on the most recent episode of the State Media podcast that he thinks it will be Brian Hartline and it could happen within the next two weeks. Hack was told he absolutely nailed the interview. Just another random opinion out there.
