I think you have 6 guys (Happ, Busch, Hoerner, Swanson, Steele, Shota) that based on career or current performance can be relied on to give you 3 WAR next year. All of those players are signed for the next 2 years (some significantly more). Morel and Seiya are pretty clearly DH only options going forward, and I'd prefer not to have both of them around. Getting rid of Seiya frees up money, Morel probably brings back more capital. For the other two outfield spots you have Cody and PCA with Caissie and Alcantara not too far off, and the Canarios of the world still floating around. Soto is an obvious enough difference maker to pursue, but beyond that, with the uncertainty of Cody's option I don't think we need to do anything drastic here.
Catcher is a black hole, it doesn't seem like Mo Baller is going to solve that problem anytime soon, go find a solution sooner rather than later. The more creative the better, but as others have mentioned just get back to replacement level and it's basically a substantial improvement.
For third base, I think you either blow away the Rays for Paredes (including names like Shaw, Triantos, Alcantara, Ballesteros) or you go sign Chapman a year too late and figure out a long term solution later.
The starting pitching is fine. Worked through plenty of injuries and are still 9th in overall production there. I don't think moving Taillon is going to generate anything of value (other teams understand peripherals too), and hoping to free up cash for Soto seems like a fools errand. Steele/Shota/Wicks/Assad/Taillon/Brown is a perfectly acceptable base and that's before Horton, Birdsong, etc. For the bullpen, I don't know...spend whatever money you have left on more arms to throw at the problem. But feel like that solution, to the extent it exists, needs to come internally.
I'm honestly not sure if that sums up to a good team or not. Paredes/Happ/Swanson/Hoerner/Busch gets you to like...16 WAR, with the goal being around 25 (9th in baseball last year), so you'd need 9 from CF, RF, DH, and C. Pitching you're shooting for 18 or so (8th in baseball last year)....Steele/Shota/Wicks/Taillon/Assad/Brown certainly seem capable of giving you 15 as starters, which means you're kinda just asking the bullpen to not be terrible. Realistically, you need one or two of these top 100 prospects to click, and to click at a position of need. But, there's a bunch of them, it's not far fetched.
