It's just relying on a lot of hopes and ifs IMO. Last year's draft was probably one of the most impactful drafts the Bears have ever had. Coincidentally, every impactful player was offensive right after we hired an offensive mastermind at HC. (though worth pointing out they only picked 2 defensive guys, not Poles' fault Turner got hurt, but Hyppolite was an insane pick). The previous few drafts were very hit or miss. The draft will definitely help us improve but I don't know how much we can count on from it, for next year at least.
The offense should get better, Jaylon and Kyler healthy should be a huge boost (IF they can stay healthy..), but we're also talking about a team that had 7 comebacks in the last 2 minutes of games and benefitted from an huge TO differential (some skill involved but part is often luck) and one of the easiest schedules in the league. I think we needed to see the team improve more via FA to offset those factors and I don't think we're presently a better team than we were 2 months ago.
We'll see, I could end up being completely wrong on pretty much all of this.
