There will be a lot of roster turnover. My strategy would be to build the best roster possible. For these reasons:
-probably means a good 2020/2021 season
-The more good players we have before Seattle takes one, the more good players we have left after Seattle takes one. (they can only take one, so it doesn't really matter how many we expose.)
-everyone else is losing a player too (except for ####ing Vegas)
Also, you're better off spending a 1st round draft pick to acquire a player with term at the trade deadline, and exposing said player to Seattle, than spending a 1st round draft pick to influence Seattle's pick because you at least get one playoff run out of it.
