I could see it going either way. I tend to think he redshirts. But if the staff is serious about potentially starting him next year, he sure needs to play at least some this year for sure. I would strive for 4 or less to preserve the redshirt.
Whatever it may be is unknown now but there is definitely some smoke. Would be a significant loss. We'll just have to wait and see. Hope for the best at this point but tough not to be at least somewhat concerned.
I think Rees does more so than Kelly. Kelly was all about the spread when came to ND. One thing I do like about Rees is his balance with play calling between run/pass, especially for being a former qb.
