The Bears signed Michael Bush as an insurance policy in case Matt Forte held out. Now that Forte has signed a four-year deal and both running backs are ready, willing and able to play get ready for the 'pony' backfield. I could see Forte and Bush in the game together and creating all kinds of conflicts for a defense. Michael Bush is 245 lbs and could lead block for Forte. Meanwhile, Forte can go in motion and be a problem for any linebacker having to match up against him. Both Forte and Bush will be effective for screen plays and on hand-offs when either one gets motioned out of the backfield.
