I mean, I guess if you cook "underperformance" in the recipe, not cutting bait doesn't look great. Lanarch and Miranda had plenty of opportunity and didn't stick, I just don't get why you are against having more darts to throw, because you want to give unknown-outcomes a more significant opportunity.
A Rh-ed bat, who can hit lefties, and play good defense was an obvious need for the outfield. Yes, one that Martin may be able to fill, but that's just speculation--hence the need for more darts.
