The Red Sox and the Seattle Mariners are similarly situated in the sense that neither team is likely to go all-in to compete in 2021.
Each team entered the offseason looking to fill an outfield hole with the Red Sox returning lefthand-hitting Alex Verdugo and Andrew Benintendi and the Mariners returning righthhand-hitting Kyle Lewis and Mitch Haniger. The Red Sox at least partially filled their hole with righthand-hitting Hunter Renfroe.
Perhaps the Mariners will pursue Renfroe's mirror image in lefthand-hitting Kyle Schwarber, another non-tender/DFA discard who is a year younger than Renfroe. Renfroe is a 6-1, 230-pound power hitter taken out of Mississippi State with the 13th pick of the 2013 draft while Schwarber is a 6-0, 225-pound power hitter taken out of Indiana with the fourth pick of the 2014 draft. Here are their 2021 Marcel projections:
HR 389 PA, .221/.296/.465/.761, 55 R, 25 HR, 61 RBI
KS 563 PA, .233/.337/.471/.808, 74 R, 30 HR, 74 RBI
Steamer and ZiPS project 2021 WAR of 0.8 in 117 games and 1.7 in 124 games for Renfroe and 2.0 in 128 games and 2.0 in 137 games for Schwarber.
Each has a pronounced platoon split.
Of course the chances of Seattle signing Schwarber are slim (although the Mariners have already signed Schwarber's college teammate, former Red Sox Sam Travis, to a minor league contract).
