Dream Signing and a Realistic Signing by Position: Offense

Dream signing: Matt Forte, RB, Chicago Bears
Realistic signing: Bilal Powell, RB, New York Jets
Doug Martin and Lamar Miller could also be mentioned here as dream signings, but even at his older age, Forte is still the cream of the crop. He also would be a perfect complement to Latavius Murray.
More realistically, the Raiders could look at a back such as Bilal Powell. Only 27 years old, Powell thrives in the pass game, an area where Murray struggles. Ronnie Hillman could also be an option.
