The one take on Cruz to CF that I think I can will myself into agreeing with is the kind of wait and see approach that is contingent on the offseason. I don't like the positional tradeoff at all and I don't think it's the best thing to throw this in a player's lap out of nowhere in the middle of a season where things went sideways for the MLB team because the GM sucks and the owner is worse.
But it is still within the cards that Cruz can't give you enough back to remain at SS, and he should have the tools to make it work in CF. It was always potentially in the cards for him, so we'll see.
It also doesn't need to be reiterated that we can't develop for shit, as others are noting, and that what I am about to say is most ridiculous at all and deserves no benefit of the doubt WHATSOEVER. That said...
If the team is making the decision that Cruz to CF is the only viable way to try and solve CF because of the market, AND THEN is also going to really spend money to improve the offense and sure up depth as needed, that's the scenario where I am most willing to ride with the decision. That means Anthony Santander or Teoscar Hernandez almost as a starting point, which is frankly a ludicrous thought.
But I don't see any real alternative situations. At CF, maybe you can pull off some kind of improbable trade for a guy like Varsho, but that's really the main trade option out there. Maybe you pay the slight premium for Bader and it works ok. That's basically it for CF options. There's nothing else internally, so if it's just a matter of making a big move now to try and set up the opportunity to really add the needed offensive talent this winter, then I'm willing to overlook what I see as a kind of short-sighted and self-inflicted problem.
