Rex Ryan blasts Cowboys defense for team's struggles: 'This defense stinks' 

Sunday night's 34-26 loss to the Minnesota Vikings crushed the postseason hopes of the Dallas Cowboys. And while there's still one unlikely path forward that would require winning out and the Eagles losing the rest of their games, Dallas will most likely be at home in January again. 

Though they briefly turned the corner, former NFL coach and defensive guru Rex Ryan never believed in the Cowboys. He even explained the glaring issue with a team that possesses one of the best offenses in the league on ESPN's "Get Up" on Monday morning. 

When asked what's been the Cowboys' main issue, Ryan emphatically responded that it's "their defense, 100%" before elaborating further. 

Rex Ryan pulled no punches while criticizing the Cowboys defense

"This is a Super Bowl-caliber offense. We've seen it all year, but this defense stinks. They made J.J. McCarthy look like Fran Tarkenton," said Ryan to open up his rant on the Dallas defense.

He then went further, turning his attention to the Cowboys coaching staff. 

"Physically, they're not what they were," Ryan said. "They moved on from [Micah] Parsons, but you made some trades that helped your team. However, I don't know what it is, whether it's the scheme or the fact, like you're either coaching it or allowing it to happen."
