I think you're right about Wilson and trading down. Douglas is not going to do that because both quarterbacks won't have the same grade. Just doesn't happen that way at that position. It's too important a pick, too important a position to play the either/or game with guys. If Douglas trades down, it's because he's not picking a quarterback.
As for the boldface font, this is quite possible, but your first scenario where they sign Schuster is more likely, I think. They're likely not going to pay Davis and Crowder both. Crowder's only one million dollars in dead cap money vs. 11.5 million dollars if he remains on the roster. He's likely gone unless he signs a real team-friendly extension, which is always possible. Flexibility is the name of the game here, one thinks, as the Davises and Schusters of the world are very good but not quite top-flight and free agency will inflate their market value rather than temper it. Interesting to see how it plays out.
I like Corey Davis as a receiver, though the knock on him is that he doesn't separate from press coverage the best and he is prone to miss time. I think Schuster is a slot guy only -- during the year without AB he didn't win one-on-one on the outside. I'd rather not sign him and go for a cheaper guy out of the slot. You kind of know what you have with Crowder, but his injury history is spotty at best. Godwin is too expensive, probably best in the slot, and not a 1A. Evans deflects a lot of pressure off of him. Anyway, it'll be interesting for sure. Given my analysis and lukewarm support of the receivers, I'd like to see them draft one and have him under contract control for a bit. But that's me. We'll see what they do.
