I don't think there is any doubt where the uncertainty starts... it's at #3, and the enemy is us. Lawrence goes to the Jags, and the Jets will take a QB and move Darnold (or alternately, they keep Darnold and trade down and someone else takes the second QB here. Those that think Sewell will get taken by the team who took Bechton last year... are on crack).
Then we come up and absolutely no one knows what we'll do... good thing too, because even we don't know what we'll do... And that's when the fun begins, because we are the hinge point of the first round. The amount of trade offers that we'll get for this pick will be staggering... because THIS pick determines the entire first round.
We'll have Atlanta on one phone (because they are desperate for their choice at QB), and four other teams on various lines... all bidding against one another. In this scenario, if we take Sewell, it's because we are in absolute love with him... because Atlanta wants a QB and will give us something... just to move up and insure they get the one they want. We won't take a WR here, because if we trade with Atlanta... all of our options will still be on the board.
In my head... I see a 99% chance that we trade out of this pick... even if we are in love with Sewell or Chase/Smith.
