I want to preface my comments by saying I understand that Lacy will often make his cut to where ever he finds a hole and when he can’t find a hole anywhere he simply keeps stringing the play out looking for an opening. That said Lacy is more effective when he is running up the middle instead of outside. His longest run is considered to be an outside run but he cut back toward the middle of the line to break open.

Also running to the left is a losing proposition. One of the reasons I hated the "I'm not a conservative coach" McCarthy call when they had Lacy run left when they needed 1 yard for a first down. That would have been the game if they had Lacy go right up the middle for 2 yards.
