The Bills are expected to let free agent DL Alex Carrington hit the market. As a versatile down lineman who turns 27 in June, Carrington could be a value pickup for a savvy team. He missed most of last season with a torn quad, but was a highly efficient interior pass rusher in 2012 and can play both tackle and end. Perhaps new Browns coach Mike Pettine will pursue Carrington to rush the passer in sub-packages. Pettine was his defensive coordinator in Buffalo.
