A - Why would you have that concern? Do you think if you believe it's a potential issue, the FO doesn't? And, moreover, if the FO doesn't, do you think you're right and they're wrong? (In a lot of cases, that might be true, but in this one with this FO?) B - They don't really need to do anything and picking up said "impact guy for the playoffs" isn't actually going to move the needle and improve this team's chances of doing anything. Especially, if, as you say, they've made it until late July without regressing (with respect to your concern about whether they keep pitching like this until the deadline, how that impacts this team's chances of putting up a historically good regular season, and whether that'd preclude them from making a move - even if that happens, then they'd be through 2/3 of the season with the same absurdly good results). It'd be fun if we can get a really good one, and would likely improve the long term outlook of the rotation, but it really isn't an issue and shouldn't cause any concern (even within the context that you're talking about).
