In this day and age, where recruits arrive on campus already known commodities, players are expected to make an impact right away. However, not all of them are mentally and physically capable of making an immediate contribution.
It takes a lot for a recruit to be "college ready," which is why it's a remarkable feat for the following 2015 recruits to make a list such as this one. An offensive tackle has the size and strength to help block for a college offense right now, while a pair of cornerbacks have the size and instincts to win a nickel role.
Also, a receiver has the speed and playmaking ability to cause headaches for college defensive coordinators this season.
