In hindsight, maye- yes. You'd have to hit on every move and have the current team not slump.
IMO, the types of "now" moves they might have tried were the ones like Castillo, but only if we extended him like SEA did and Civale, who had multiple years left.
The teams were not good enough for giving up good prospects for rentals. You save those moves for seasons like 2018 and Nate.
The one Bloom season worthy of that was 2021, when we got Schwarber, Robles, Davis, Shaw and later Iggy. We should have gotten a solid SP'er or closer.
I was for buying in 2023, but not giving top prospects for rentals.
