The Mariners need at least two starting caliber outfielders, Seager to be the Seager from 2013-17 and not from 2018, literally anyone other than Ryon Healy at 1B, a couple starting pitchers, a couple relievers, a DH type bat that can replicate Cruz's production and they have to get it with almost no money to spend and no prospects to give up. Even if they manage to get all of that they still might only be the third best team in the division.
