I believe it's up to the players to clearly separate themselves from the pack in practice, ESPECIALLY at QB. We aren't privy to all of the details that arise during practice and a player's star rating coming in is no positive indication of his ability to play right away. Having said this, has BK "missed" on a player or two being ready right away? Probably. But there's always a steep learning curve in one's first year of college with all the adjustments one must make, both in being a student and a football player.
