In his first year as OC in Dallas Moore had the #1 rated offense in the league.
In his second year he had the team back there until massive injuries, including the starting QB hit the team. Even then he has them ranked in the top half of the NFL (12th I think), and that is with an entire OL that is out for the year (and starting 2 UDFA rookie tackles) and having lost even the backup QB for a few games.
He lost his starting QB, his all-pro LT, his top 10 RT, his all-pro RG, his all-pro center (to retirement), and the other OL have been in and out of the lineup.
With that, last week his offense put up over 500 yards and scored 37 points against a division rival.
The guy is doing one hell of a job with the offense and Dallas is lucky to have locked him up long term.
Get the injured guys back and give him a half-decent defense, and Dallas will win a lot of games.
