The experiment of putting Ty Montgomery at running back wasn’t really a failure.  He was effective, but he couldn’t stay healthy.  Montgomery was limited to 71 carries in eight games last season while he struggled with rib and wrist injuries.  Surgery ended his season.  With the development of Jamal Williams, Aaron Jones and Devante Mays, a move to the slot, or wide receiver, might be better for the man who still wears uniform number-88.  One strong argument for the move is that Montgomery has averaged eight-point-24 yards after the catch over the last two seasons — 10th-best among all N-F-L players.
