It seems as if teams so far are having a hard time getting Hurts and the Eagle's offense. It definitely seems like an RPO version and Hurts is having success on designed runs which has opened up their running game. When they don't run he has bought himself enough time running around to hit some stuff down the field. With that said they try and get the ball out of his hands mostly when they do pass with slants and a lot of stuff over the short middle.
The Eagles look to have a pretty good offensive line so far. I'd be worried about Hurts and the style they play but with that RPO mess the NFL figures it out eventually and it's really sooner rather than later. On top of that we have a guy named Micah Parsons who can chase Hurts down and really cause problems, but he causes problems for everybody.
