If I were running the Bears, I would accept a trade with the Pats or Commanders, use the pick swap to draft Harrison, then draft Daniels or Penix at #10. There's not that big a difference in talent in this stacked draft class; any of them could be successful in the right system. But right now, it's hard to say that they have everything they need to make anyone successful.
And yeah, I think they should cut ties with Fields because he's not getting any younger or cheaper. If they could get a 2nd or 3rd for Fields, they could use the pick to bolster the O line.
