Hurts is interesting to me because I wasn't really high on him, but he is having one heck of a year. One thing to consider about Hurts, he wasn't a first round pick so the Eagles have him dirt cheap for this year and next year. They won't have to make a decision on him for another season or so.
Fields is interesting because at OSU he was more of a pocket passer. In the NFL (and primarily because the Bears WR's are terrible) Fields running ability has been his biggest asset. I think when the called QB run plays become a staple of your offense, the QB is in danger long term. If the Bears get to a point where they are doing far less QB run and allowing Fields to scramble when needed, he will be in a better place.
