Good stuff. I don't know the details, so it's good hearing from a Philly fan who does.
Also, people do not understand that the biggest reason Philly won the super bowl was the #1 D in the NFL. They then proceeded to let several D players walk, including stalwarts Milton Williams, Slay, and Sweat. As well as some quality backups in Isiaiah Rogers, Avonte Maddox, Brandon Graham(retired), Oren Burks. That's a ton of contributors to use.
And while so many were singing the praises of Hurts, he passed for all of 2,903 yds, good for the 29th best passing O. That is simply unsustainable.
So, what happened? Well, I surmise that Hurts' injuries are limiting his running. Leg and Shoulder. He got beat up good this year running that RPO, and cracks are starting to appear in the armor.
In the RPO, what is conveniently forgotten is that when the QB pitches to the RB at the last second, he gets creamed. Which is why most QBs are strictly limited in running the RPO.
