Teams will have an idea of who Seattle might be looking at before they get to the expansion draft. That's why you'll see deals made where the expansion team gets something in exchange for agreeing not to pick some player. Or, they'll talk and the established team will say "we want you to take this player, here's something for you if you'll do that." It'll be the same with us. Seattle can only take one player; you're basically asking who on the unprotected list you think you can't live without and trying to steer Seattle to everyone else. Throw on all the rules that apply to who Seattle has to take (# of players at each position, % of cap) and it kind of whittles down who will be under serious consideration.

Let's get through this season and see what our roster looks like when we're done with the playoffs, then worry about what to do with the expansion draft. Just like all the hot takes about this team's direction and how certain players were doing through 6 games, a lot of things can and will change in the months ahead and we might well decide yeah, I'm really OK without ____ being here.
