Cowboys owner Jerry Jones promised back on Jan. 2 that Dallas would be making some organizational changes and on Tuesday the Cowboys made a big one when they fired second-year defensive coordinator Rob Ryan.

“I can assure you guys — I can assure our fans — it’s going to be very uncomfortable for the next few weeks and months at Valley Ranch,” Jones said in a recent radio interview.

In two seasons as the Cowboys DC, Ryan put together defenses that ranked 14th (2011) and 19th (2012) in the league. Prior to his two-year stint in Dallas, Ryan was a defensive coordinator with both the Browns (2009-10) and the Raiders (2004-08).

Ryan’s status with the team had been tenuous since the Cowboys season ended after their 28-18 season-ending loss to Washington on Dec. 30. In that game, Redskins rookie RB Alfred Morris ran for a career-high 200 yards and three touchdowns. A win would have sent the Cowboys to the playoffs.

But I do believe Rob had the best quote of the night after his firing.

“I inherited a team that was 31st in the league in defense and made them better,” Ryan told ESPNDallas.com’s Tim MacMahon. “I (expletive) made them a hell of a lot better. I’ll be out of work for like five minutes.”

You know Rob, once you get over that self confidence issue, there’s no stopping you!
