1. The Washington Commanders
One of the most obvious trade partners for the Bears would be the Washington Commanders, who recently hired Williams' collegiate offensive coordinator Kliff Kingsbury to the same position. With the second overall pick, this would result in the shortest possible trade back for the Bears, leaving them in striking range to select a plethora of elite players, including non-Williams QB prospects.
It is hard to forecast what a trade just one spot back would look like - although it would certainly be more than the Bears gave up to move from third to second overall in the 2017 NFL Draft, where they selected quarterback Mitchell Trubisky. Still, the Commanders want Williams, and with new ownership, it would make sense for this group to try to put their stamp on the franchise early.
In return, the Bears would likely be focused on recouping a second-round pick this year, which was sent to Washington at the trade deadline for Montez Sweat. To add another top-50 selection would be great, but it is hard to foresee this trade going through without at least a future first-round pick. At first glance, this might not seem like the most impressive haul, but adding multiple premium selections while falling back only one spot could be a successful draft formula.
