There is undoubtedly some validity to the fact that Wentz's reckless style puts him in harm's way. I was talking to my former roommate who is a huge Eagles fan about this a couple weeks back and I was comparing him to Romo in the way that their escapability is/was their greatest trait. While Wentz's body is far more able to sustain hits than Romo's ever was, QBs playing this style no matter their size (including Roethlisberger to some degree) will sustain injuries more often than those who do not (i.e. both Mannings, Brady, etc.).
Rodgers comes to mind as one of the greatest in NFL history when it comes to elusiveness but he is better at avoiding hits especially past the LOS. Wentz will have to adjust and, at least IMO, this will take some of the shine off his game until he's able to fix some of the accuracy issues he has.
His future is obviously extremely bright, but he'll have to learn to play smarter, especially considering he's likely to be at least marginally less explosive with his legs following the injury.
