Sewell is not getting past Cincinnati. He's the Quenton Nelson of this draft class but at tackle, probably end up as All-Pro. I think Broncos should take whatever drops to them where they are and it'll be at worst a top-end receiver like Pitts for TE or one of the plethora of top WRs.
WRT the draft order Jags won't pass on Lawrence so that's him sealed to them, I can't see the Jets going with Darnold so Zach Wilson is almost a lock at 2 and we wouldn't give up two firsts to move up for Sewell (as we've got Trent Williams at LT) or Devonta Smith/Jaylen Waddle as WR isn't a massive hole need either. So we're definitely going up for QB. (Plus you don't give up that much capital for receivers or non-elite edge players)
Falcons will take either Sewell or a QB at 4 depending on how they feel about Matt Ryan's future. With 3 QBs gone the likelihood is it'll be best case scenario McCorkle Jones or Trey Lance. Lance could be interesting for them as he's very much a project and with Ryan there he has no need to immediately start and get ripped to shreds by critics/fans
