By Josh Hill - Mar 8th, 2014 at 11:01 am The Chicago Bears are looking to improve their roster as a whole — with an emphasis on defensive positions — and this upcoming free agency period could be big for the team. One name that is a late arrival to the party is recently released Saints speedster Darren Sproles. According to NFL scribe Dan Pompei, the Bears and Sproles could make a natural fit, especially considering they’re going to be losing Devin Hester to free agency this upcoming week. Per Pompei: Sproles would be an outstanding fit for the Bears. He could replace Devin Hester as the return man. And he would be an excellent change of pace back who could contribute as a receiver out of the backfield. He is 30 years old, but he still played very well last year. I think Marc Trestman could do some really creative things with a player like Sproles. While it makes sense for the Bears to add a speedy offensive threat like Sproles, Pompei points out some flaws. From constraints that may be put on him in Marc Trestman’s offense to the issue of other teams offering more money, the idea of Sproles landing in Chicago isn’t a that high. It’s not impossible though and will likely be something that is explored when the Free Agent tampering period opens.
