I'm pretty sure the 7 INTs thing is fake...I keep seeing this blurb about him getting benched on 7v7 because he threw 7 consecutive INTs or something, its always worded the exact same way and makes no sense.
It is true though based on all reports that he struggled on one of the days during OTAs. Here is a blurb from The Athletic:
https://www.nytimes.com/athletic/5516383/2024/05/23/chicago-bears-caleb-williams-ota/
What doesn't typically get mentioned:
1) Reports suggest that the offense was actually better than the defense the day before this report
2) This is a new offense that everyone is learning going against an established defense and a rookie QB getting acclimated to the speed of the NFL
3) It's literally May and there's really no point in taking anything away from a couple of early practices run without pads.
Basically yes it sounds like he struggled, possibly mightily, but I am pretty confident in saying that it should not change your expectations of Caleb or the Bears at all. If Caleb absolutely dominated, it shouldn't change your expectations either.
