There's a reason the word sleeper bounces around NFL draft coverage like a power running back bulldozing one defender after another.
Every installment of the annual talent grab sees studs slip through the cracks. Last season's Offensive Rookie of the Year, New Orleans Saints running back Alvin Kamara, wasn't taken until the 67th pick. The Kansas City Chiefs running back Kareem Hunt went 19 selections later, then lead the freshman class with 1,327 rushing yards.
As much as scouts, analysts and fans like to think they know about the draft, it's still a glorified guessing game.
