Bills vs. Chiefs: which Kansas City player would help Buffalo most?

Congratulations! You have inherited the GM post of the Buffalo Bills from Doug Whaley for a day. John Dorsey, GM of the Kansas City Chiefs, gives you a call and tells you that to welcome you to your first NFL gig, he's going to let you pick one player off of his roster to add to the roster you inherited from Whaley. Who do you pick?

Kansas City has a lot of elite players. Jamaal Charles is a fantastic running back. Dwayne Bowe is a pretty dang good receiver. Dontari Poe is emerging as a star on the defensive line, and the best pair of pass rushers reside on this roster in Tamba Hali and Justin Houston. Derrick Johnson would make a fantastic partner-in-crime for Kiko Alonso, no? Brandon Flowers would solidify the team's cornerback position, and hey - it'd be fascinating to see Eric Berry and Stevie Johnson coexist as teammates, right?

Then again, maybe you're focused simply on filling holes. The Chiefs have a trio of versatile interior offensive linemen that you might consider an upgrade on Doug Legursky. Maybe you're fed up with the quarterback carousel and would like Alex Smith to try to lead the Bills to the post-season.

The choice is yours, boss. Who are you making the newest member of the Bills?
