They certainly had a plan. It's one thing to disagree with it, but saying they did not even have a plan is not accurate. If saying that is just hyperbole, fine, but they had a plan and injury contingency plans at every position.
IMO, the problem was "the plan" went wrong at too many positions, and many of the contingencies plans failed. The back-up SP'er plan collapsed due to needing to go 3-4 deep for much of the season- having to pull from the pen, at times (Houck & Whitlock.)
Out of 144 games, we saw 53 starts from these "back-ups!"
14 Wink
12 Crawford
9 Whitlock
8 Bello
4 Houck
3 Davis & Seabold
That's 37%. This caused not only the need to rob from the pen but to tax them with more IP than should have been planned for. Our pen injuries were also excessive, and we did have some long injuries, including Taylor, Houck, Strahm, Barnes and marginal pitchers like Brasier and others. Even Whitlock & Schreiber missed time. I'm not making excuses. We should have added more proven arms, and the Diekman & Robles choice were a failures, but it was a plan.
The rest of the plan that went wrong, included:
1B: The plan was to go with a player who had an OPS over .800 in his first 500+ PAs- thinking there was a chance he'd build off his strong second half of 2021 and maybe get even better. The back up plan was Casas, who was widely viewed as being ML ready by May, at the latest (exactly the length of rope a failing Dalbec might require.) Not having a true 3rd option could be viewed as "no plan," I agree, but I think the idea was that Dalbec and Casas could get us to the trade deadline. Needing to use Franchy and Arroyo at 1B did not work well.
2B: Story was a late signing- perhaps an afer thought forced on Bloom. Maybe someday we will know the workings behind that deal. Having an oft-injured Arroyo as the back-up was still a pretty solid plan, and Downs was viewed as a capable deep depth option- at least decent on D.
CF: Kike was viewed as a solid CF'er. Big plus on D and decent on O. His injuries crippled us, and I would agree that having Duran as the back-up plan was a mistake, but seeing the 4th OF'er as the biggest hole on a team is not all that short-sighted.
RF: JBJ was the plan, and the plan failed spectacularly, here. Many of us foresaw the failure, so it's easy to label it as "no plan," but it was a plan. Refsnyder ended up being an unforeseen nice depth piece added by Bloom, but he is largely overlooked by those focused on mostly the bad moves.
DH: Counting on JD was likely a forced choice and not a bad plan.
The rotation plan was probably something like this:
Sale
Nate
Wacha
Pivetta
Hill
(Paxton joining in late July or August to take over for a likely injury or decline by one of the 5.)
Crawford, Seabold, Winckowski and eventually Bello in the wings, but maybe not ready in April. (Houck and Whitlock as emergency help)
That's not a horrible plan. IMO, it's not even a bad one.
The early Sale injury hurt- big time. One can rightfully argue, it should have been expected and planned for, but I think we did have a plan: Paxton later in the season and some ML ready prospects earlier in the year and Whitlock or Houck as emergency options.
As it turned out, we needed to use both Houck and Whitlock for 13 starts, which severely taxed and shortened the pen early in the season. This put us in a deep hole, we never got out of. Maybe we could have tried Crawford or Wink earlier, instead of taking Houck- then Whitlock out of the pen, and those choices would likely be debated all year long, too.
Has Bloom been given $10-20M more in budget spending, maybe we'd have signed- a couple more or better RP'ers than we did sign. I doubt we'd have added a 1Bman like Bell, but we might have signed Pham.
One can argue that signing someone else besides Story would have been a better plan, but that was a plan.
One can argue not trading Renfroe, which also would have allowed us to spend more on the pen or on Pham was a better plan, but that too was a plan.
