Bohm, to his credit, is better defensively than Suarez. But since they are both essentially playing on one-year deals and Bohm has actually had trouble staying healthy even being younger, I would pay an extra $4.8 million for the guy with 3.6 WAR and 49 HRS over the guy with 1.5 WAR, especially since you'd also get a return on Bohm (of some kind). I just don't believe Bohm has another level of offensive production to come.
They could have done it with or without the Bader/Garcia choice (I'm fine not signing Bader since Garcia is just as good as RF, they are trying to play Crawford in CF and Bader is still no more likely to hit than Garcia).
OTOH, Suarez's power comes with an appalling OBP and walk rate - more of the same in an offense that already added Garcia, and Bader wasn't a disciplined hitter either.. While Bohm is not exactly an on-base machine, his bat-to-ball and RISP skills are not nothing. He wasn't better with RISP last year though, because of course that is not really a skill.
Certainly if Suarez had taken every AB Bohm got last year the Phllies would have scored a lot more runs (Bohm had 59 RBIs with no consistent spot in the order, but mostly 3-4-5; Suarez had 118 hitting 4-5-6 and 87 of those were for Arizona). I imagine his production in Seattle (.682 OPS) scared off most teams and kept him from getting a multi-year deal though it was probably more a slump and the trade than a sign he's done.
