I don’t think Newton is any more likely to get hurt than JA. They have a similar running style and I think will be used in similar ways in their offenses. Both have been so effective from the pocket, that I don’t expect to see either run very much except in the red zone.
Murphy reminds me of Flutie and R Wilson...he just never seems to take a hit. As you point out, very different from Cam and JA, who seem to relish contact...
