Each year, some undrafted prospects will make a strong impact as rookies in the NFL.
Arizona State's Vontaze Burfict is a prime example from 2012, because he ended up as the Cincinnati Bengals' leading tackler.
A year earlier, Stanford receiver Doug Baldwin went undrafted and was picked up by the Seattle Seahawks. He finished as the team's leading receiver in yards, touchdowns and receptions.
So, we can't discount the efforts of any college star with NFL potential.
One guy we'll check out ahead is Nevada's Stefphon Jefferson. In a draft that doesn't present any top-10 prospects at running back, that lumps most into the middle rounds. Factor in pro football as a pass-oriented league and it's easy for Jefferson to go unnoticed.
And he's not the only one who will during this draft season.
