He played in a one-read friendly offense in college and never had to read the full field. That and his lack of pocket awareness were the big questions on him. He obviously hasn't had the chance to improve these things much with the Bears.
Other than your usual meatball homerism, what evidence...
I wouldn't say Fields is not a real QB. He's just an incomplete one at this point and needs to learn how to stay in the pocket and extend plays with his eyes as well as his legs. But better protection will help with that.
The roster isn't good enough to win with Fields being decent. He would have to be great. And I don't see anything about him as a passer that's in the same universe as great. It's going to take 2-3 years of excellent talent acquisition to get them in a realistic place to compete for a Superbowl.
Teams on average have either 1 or 2 top 50 picks every year. It's not possible to build a top roster that's all, or even mostly made up of your own top 50 draft picks. Quality rosters have plenty of later 2nd/3rd/4th/late round picks on them.
Option 1: picks 9 + 53 + 61 + 64 + #1WR + #2WR...
Probably the NFL for me, mainly because there's so much turnaround, and the biggest splashes can be anywhere, not just the same few teams with the most money.
Pretty much every article I've seen about the trade has said it was a haul for the Bears. The offseason has been fairly consistently complimented so far. Someone would need to have an agenda to argue to the contrary at this point.
It's not what's at the end of your wrists it's what's between your legs, and the Sex Cannon is the only Chicago Bears QB to wear that hat since the end of the Cold War!
I'm all for investing heavily on the OL and DL in the draft and a few sensible FA pickups, but don't trade the farm for huge contracts. Keep the powder dry for being able to invest sensibly over the coming few years as you build the roster through the draft.
And I know a lot of people don't...
