I would be happy to see a bit of a roster shakeup for 2021 that would make us competitive for a playoff spot (why not think positively) by bringing in some younger players and looking for some quality young starting and relief pitchers.
My shakeup in the infield would be to consider moving Devers to 1st (probably won't happen) and Dalbec to third. Bogaerts is our anchor at SS, Arroyo is looking like the young 2nd baseman we've needed for the last 3 years
My shakeup in the outfield would involve trading Beni, Keeping JBJ at center (probably not going to happen) and leaving Verdugo in RF. If JBJ goes I would give Duran an opportunity and use Chavis as the LF. I would use Munoz as backup in LF and RF and Lin as backup in CF. Holding out hope for another quality right handed hitting outfielder in place for Chavis.
No change at catcher
I would shake up the starting pitching by moving Eovaldi to a high leverage Relief role. Sale is not going anywhere but probably can't help us until June at the earliest. We have to hope E-Rod makes it back and Perez has looked like a reasonable 4th or 5th starter. We need to find at least one starter (preferrably two) from Pivetta, Houck, Mata, Seabold and Ward. . Then Bloom has to find us 2 decent quality starters. Starters aren't durable so having 6 to start with Sale returning sounds good to me.
Relief pitching with Eovaldi, Barnes, Hernandez, Taylor and Valdez supplemented by two quality arms would allow for competitiveness. Brice, Brewer, Brasier and Weber as alternates would be reasonable. I look to move the rest.
Our DH position has been very unproductive this year. Your value is indicated by your stats. My shakeup would be to trade Martinez and find a younger replacement.
That leaves us with the thought of what to do about Downs, Potts, Casas and Groome, all of which are knocking on the ML door. Downs in particular could be ready in 2021 and will we have a slot for him. Same for Casas in 2022.
It's the hard ass approach to the roster, but the management has to be willing to cut ties with unproductive players and build a team where everyone in the lineup contributes. It's not as easy as waving a magic wand, but I believe Bloom is the guy that will pursue a policy that requires performance from players
