I mean, this could all go sideways, of course, but I really think Fields has a Josh Allen ascendancy.
3700 yards passing
35 TDs/13 INTs
1,000 yards rushing (1068 to be exact)
Passer rating: 107
8.3 sack %
65% completion percentage. (Allen had a worse completion percentage than Fields in his 2nd year, a fantastic one in his third year, far above what he's done since. If Fields improves it at the rate Allen did, it would have been +70%.
That's my high end prediction. I think it's very possible and if it happens, the Bears will win 12 games, easy.
