The following is the NCAA's definition. You should definitely discuss the program's redshirt policies with the recruiting coach. Redshirt decisions are usually made before the season starts. But, it's really going to be up to each coaching staff and what their player needs are, the talent that shows up in the Fall, the injuries that may occur, etc. IMO, no guarantees.

NCAA Redshirt definition —In Divisions I or II, redshirting refers to someone who is enrolled full-time at a school but does not play for an entire academic year for the sole purpose of saving a season. A redshirt does not play in any college game or scrimmage in a given sport for an entire academic year, even though that student is eligible. If you do not play in a sport the entire academic year, you have not used a season of competition. However, if you play in even one second of a game as a college athlete, you are not a redshirt. Redshirting does not exist in Division III because in Division III, if you play or practice after you have enrolled as a fulltime student, you use one of your four seasons of competition.
