A hot topic as of late is the roster turnover after next season. If you take a solid look at the roster, it's a reality that 7-10 guys could declare for the draft. Descending Order of likeliness.
McMillan (obviously), Lewis, Hubbard, Samuel, Conley, Price, Barrett, Booker, Jones, Pridgeon.
Then there are guys like Noah Brown (didn't get injured he would be automatic), Holmes, Hooker, Worley, and whoever starts at DT.
The better bowl game OSU is in, expect more players declaring. If they make a title run, it could be a mass exodus like this year.
