Our Rookie Buzz series has had some hits and misses. It's lost two of the original four members to season-ending injury, but in the end, it appears that NFC North teams will be getting early-season contributions from a dozen 2012 draft picks, depending on health. Let's take a look at who the Chicago Bears, Detroit Lions, Green Bay Packers and Minnesota Vikings appear to be counting on:
Bears defensive end Shea McClellin
Likely role: Nickel pass-rusher
Comment: As we've discussed, the Bears could follow a playing-time model similar to what the San Francisco 49ers did with 2011 top pick Aldon Smith: Less than 50 percent, but hopeful of high production in small doses.
Bears receiver Alshon Jeffery
Likely role: No. 3 or No. 4 receiver
Comment: Has been productive in the preseason and is an especially big target down the seam.
Bears tight end Evan Rodriguez
Likely role: No. 3 tight end and/or H-back
Comment: Rodriguez has proved to be quick down the field and a nifty runner once he makes the catch.
Lions cornerback Bill Bentley
Likely role: Starter or nickel cornerback
Comment: Bentley's had a few roller-coaster trips on the Lions' depth chart, but if he is healthy he figures to be one of the Lions' top three cornerbacks.
Packers linebacker Nick Perry
Likely role: Starting outside linebacker
Comment: He's gotten almost every snap with the starters this summer, mostly to give him every opportunity to learn a new position. But his pass-rush skills are evident.
Packers defensive lineman Jerel Worthy
Likely role: Defensive tackle in the nickel
Comment: The Packers play their nickel defense more often than their base, which makes Worthy a quasi-starter.
Packers cornerback Casey Hayward
Likely role: No. 2, 3 or 4 cornerback
Comment: Like Bentley, he's made a few trips up and down the depth chart. But he has a chance to start soon opposite Tramon Williams.
Packers safety Jerron McMillian
Likely role: Nickel safety
Vikings offensive lineman Matt Kalil
Likely role: Starting left tackle
Comment: This assignment has never been in doubt.
Vikings safety Harrison Smith
Likely role: Starter
Comment: He hasn't let go of a spot he earned midway through the preseason.
Vikings cornerback Josh Robinson
Likely role: No. 3 or No. 4 cornerback
Comment: Dealing with a concussion but has outplayed veteran Chris Carr to be the nickelback.
Vikings place-kicker Blair Walsh
Likely role: Starter
Comment: Has demonstrated a powerful and accurate leg this summer.
