Pittsburgh Steelers trust that DeAngelo Williams will embrace new role

PHOENIX -- General manager Kevin Colbert admitted there is some unknown when it comes to the Pittsburgh Steelers' only free-agent signing as far as outside players. And it has little or nothing to do with running back DeAngelo Williams (pictured) residing on the wrong side of 30 or the fact that he will be entering his 10th NFL season in 2015. The question with Williams is how he will adjust to backing up Le'Veon Bell, a role that could come with fluctuating playing time and limited touches.
