We don't know what Poles will do. We do know that the Bears need starters at RT, DT, DE and maybe at CB. First 4 picks could go that way.
But there are still decent FAs still out there that could be signed that could get the Bears through '23 and allow Poles to really go after the BPA like a HB or WR early. Positions that really don't look like huge needs in comparison to what the Bears have today. But realize that Foreman, Mooney and Claypool all have deals expiring in '23.
I am not saying that the Bears will draft a WR/HB - right now it looks like one of the tackles will go at 9, but Poles is unpredictable.
