But who are these "kids" who deserve a chance in CF?
Moniak is, if not a bust, a guy who almost certainly needs a full season in AAA, and you're still playing long odds that he's anything.
Quinn may have more mileage left on him than his age suggests given his actual games played, but he's probably not a starting CF either, especially with defense that isn't as good as you'd think it would be given his physical ability. The odds of him staying healthy enough to find his bat remain low, if he can even find his bat at all. Best to accept him for what he is until his salary rises.
Haseley deserves more of a look even if the previous regime - and most of MLB - has already decided his ceiling is 4th OF, but that's a straw man, because he wasn't allowed to be the high end of the platoon last year, and he's not likely to be the starting CF this year. They are either going to sign an OF who takes 200 ABs away from him in LF or sign an OF who takes 200 ABs away from him in CF, so it doesn't really matter which one happens.
I still don't see how they sign a SS, a starter and a reliever anyway, let alone an OF. ElP's Didi, JBJ and Hamels scenario is still $26 million, which would take them to last year's payroll, and close to the CBT. Still seems unlikely they do that.
