Once considered to have some of the best chemistry in the league, Jay Cutler and Brandon Marshall seemed to have fallen out in their last year together in Chicago.
When Phil Emery took over as general manager of the Chicago Bears, he seemed to understand that the league was becoming more and more dynamic from an offensive standpoint, and that his predecessor, Jerry Angelo, had deeply entrenched the team in a very old-school, traditionally defensive philosophy.
Not to say that Angelo's approach was outdated-- we still know that a dominant defense can win championships, but that ship seemed to have sailed a few years earlier in Chicago, and it seemed that things had simply become stagnant.
