Extended Spring? They have 2-3 position prospects who may see significant time in an extended spring scenario (Garcia, Kieboom, and maybe Robles). Beyond that, they will temporize with short, flippable signings. Nothing is stopping them from signing a starting OF and another infielder. They can do that with a reasonable financial commitment that will not block any development. If there's pleasant surprises in terms of health and performance, then they will be in a position for minor moves at the deadline.
And literally no combination of those signings realistically puts them in a playoff hunt.
2022 will be about developing at the major league level and flipping short term contracts to build up the farm. If by some series of miracles we are actually in the playoff hunt at the deadline, then maybe we can talk about trading prospects for players. Until then, there is zero point.
