If fields runs as much as he did last year, I don't think he survives the season. He was looking pretty beat up by the end of the year.
While I agree with you, I think it's very unlikely he runs in the same way this year. Will still run a lot, just smarter. To me he was fighting to show he even belonged as a starter if you think back to before he caught fire. That team had absolutely nothing to throw to and zero protection. I felt like the team as a whole was desperate, and after seeing lightning a couple times they just kept going back to it because that's all that worked.
DJ Moore is a damn stud. Mooney should be healthy and has plenty of talent - will likely look much better as a number 2. They also drafted the best offensive lineman by a mile in my opinion. These are all reasons that Fields will be much more productive as a passer. Keep in mind, coming out of highschool Fields was spanking T-Law in all the accuracy competitions in qb camps. The guy can throw and has a good head on his shoulders. I see an easy case for making a nice jump this year as we've seen from several young QB's lately.
Fields is my QB target this year, and I am taking him at cost every time he is there. He singlehandedly won me two championships last year, so I admit I am slightly too in love. But I watched every game last year and it was so obvious he had nothing around him and was playing superman ball. Chicago made progress this off-season in a lot of those areas. I think he ends up QB1.
