This. In a vacuum, should a team that is 2 games above 500, with a minus-50ish run differential be sellers? Yeah. Probably. But we aren't living in a vacuum. We have a young team that hasn't had any success in years. We are a game back of a team that is projected to have a much better 2nd half than first half, but crazy things happen. Additionally, if we have a chance to stabilize a) our 5th starter spot and our 3rd best bullpen option and it doesn't cost us much then I say go for it Jamie Garcia does nothing for the Astros because you'd be taking a 50% win probability pitcher and replacing him with a 50% win probability pitcher. But if we can take our 20% win probability pitcher and replace him with Jamie Garcia, that could me 2 wins. That doesn't globally make Jamie Garcia a 4.0 WAR pitcher but maybe he's 4.0 TwinsWAR. Same thing on the RP side.
