Poll: Which rookie will make biggest impact?

As the NFL combine kicks off this week in Indianapolis, it's time to get your early pulse on the draft.

Even though there's no guarantees that the AFC North teams will land these players, which one do you think will produce the biggest positive impact?

  • Alabama running back Trent Richardson with the Bengals: Considered the top running back in the draft, Richardson had 1,679 yards rushing last season, breaking Mark Ingram's school record for most rushing yards in a single season, and ran for 21 touchdowns. He would take over for Cedric Benson, who is not expected to get re-signed by Cincinnati.

  • Baylor quarterback Robert Griffin III with the Browns: As a top-five pick in the draft, RG3 would probably start right away over Colt McCoy. The Heisman Trophy winner completed 72.4 percent of his passes for 3,998 yards and 36 touchdowns. He also ran for nine scores.

  • Arizona State linebacker Vontaze Burfict with the Ravens: Baltimore could be looking for the heir apparent to Ray Lewis, and Burfict's relentless motor makes him a logical candidate for that role. Burfict, the second-leading tackler at Arizona State last season, would likely step into the starting lineup next to Lewis if Jameel McClain isn't re-signed.

  • Memphis defensive tackle Dontari Poe with the Steelers: With all of the uncertainty surrounding Casey Hampton's health and contract status, Poe would have the chance to start immediately at nose tackle for the NFL's top-ranked defense. Poe, a 350-pound cog in the middle, was voted co-Most Valuable Player at Memphis last season after finishing with eight tackles for loss, five quarterback hurries and three passes defensed.
