I'm not really sure what else the Braves could do regarding starting pitching to make you think they aren't keeping an eye 3-4 years down the road. If the sheer number of legitimate prospects still working their way through the system isn't enough, how about them having spend their first rounder on yet another pitcher this year and no doubt they will spend a first rounder on it next year as well.
Their insufficient attention to this area is not a legitimate gripe.
