Getting rid of McCoy and freeing up the cap space is a no brainer. It is not that big of a step down from McCoy to Murphy at this point in McCoy's career anyway. Bills need to add a guy like Gillislee for the remainder of this year, but what is the point in keeping an expensive running back around anyway? An extra 3rd or 4th rounder next year is all the Bills are going to get. Just trade him for a 4th rounder and free up the money.
