Almost all of today's recruits do not want to hear the word "redshirt" when a school is recruiting them. Today's prospects are competitive, plus they have egos.
So playing right away is a goal many of them have, but most of them need a year of development before getting on the field in college. Others enter situations where the incumbent depth chart is simply too great to overcome. No matter the reason, many recruits in the 2014 class will redshirt this fall.
A trio of quarterbacks will be holding clipboards during the 2014 season, while a running back will not be immediately needed. Also, an offensive tackle just isn't ready to play right now.
