It is not a stretch to say he was the most impactful rookie of the entire season last year. That said, the Cowboys benefited from a last place schedule plus many other scheduling advantages...nobody they faced was coming off a bye...they faced 2 teams off MNF games...they played 4 non-div opponents in a div sandwich. This year with a 1st place schedule they were bound to be less successful than last year's 13-3 mark. Now without their stud RB and a lesser O-Line, and a likely regression by their Soph. QB without as dominant a running game to fall back on their TOP END record is likely 8-8 and out of the playoffs.
