I watched his press conference out of boredom, and it was really quite a touching video. I would recommend it to you guys. I'll be cheering for him for sure.
Murray averaged under 4 YPC in December last year, meanwhile Romo had a 133 QB rating in December. You could start at RB with that line and they would be fine.
Murray had 20 or more carries in each game in December, including 40 touches [rushes + receptions] against the Bears. Murray was a workhorse in December, took the ball out of Romo's hands a lot which led to success. They have the best line in the league bar none, they should be fine as long as the backs stay healthy.
