College coaches open each recruiting cycle with more than a thousand prospects in their recruiting database. Each position coach evaluates all of the players in his area and only has the coordinator and head coach look at selected prospects he feels could be worthy of a scholarship.
In this process—with each coach responsible for evaluating so many players—some prospects can be overlooked or "slept on," to use a common recruiting term.
Perhaps a prospect is playing out of position, has not received good coaching, has played hurt or is a late bloomer like Green Bay Packers quarterback Aaron Rodgers.
Whatever the case may be, every recruiting class has prospects who get slept on and go on to have good careers.
This year, a quarterback prospect recently outperformed the nation's best at his position at a camp but still lacks elite offers. A running back recruit is committed to a school but warrants consideration from juggernaut programs, while the most athletic cornerback in the country is without a scholarship offer.
