Add in the shoulder/elbow issues in high school (which is why he has an elongated release) it's fair to question whether or not he's going to last 10+ years.
That's one of the reasons why I don't think he will ever repeat what he did last year.
Eagles also changed over their entire medical staff which flew under the radar amidst their Super Bowl celebrations. And the early returns have not been positive.He was on his way this year.
