Every year, a few dozen collegiate underclassmen decide to forgo the remainder of their NCAA eligibility in favor of entering the NFL draft. For some, like Andrew Luck or Robert Griffin III, the early jump to the professional level is a fairly straightforward decision. If you know you will be picked in the first round, the lure of making millions is often to much to resist, especially when it means taking another season of injury risk, which could devastate their career prospects later on.
However, other players decide to make the jump for reasons that baffle the rest of us. Perhaps, with the assistance of an overzealous agent, they vastly overestimate their own draft stock. Or maybe they have discipline or academic issues that cause them to wear out their welcome at their respective universities. Regardless of the reason, inevitably each year there are players who make a major blunder when they jump early that can derail their NFL career before it even gets started.
