Allard was the 14th pick, and signed for $3,042,000, about $200K above the recommended pool value. He was not some huge over-slot guy. The Braves rolled the dice on a pitcher with injury concerns when they drafted Allard, which is another thing they have shown a willingness to do during this rebuild.
Recent draft history has shown us that guys like Groome who folks claim to be signability problems either sign anyways at near slot value, or go back into the draft and see their stock fall dramatically the next year like Appel and that other pitcher I am forgetting.
If the Braves are paying attention, they should realize they need to be drafting BPA and signing these guys to a deal near slot value. If the kid doesn't sign, the kid doesn't sign...good riddance. Use the same pick next year on a kid that wants to be a professional baseball player. Enough of this quantity over quality nonsense where they spread the money around.
