They also did a Q/A chat with Ballew.

Some of the most interesting quotes, in my opinion:
On Sims' curve being rated higher than Touki's:
"Sims throws his curveball for strikes with much more consistency. It’s also an outstanding pitch, much like that of Toussaint, but Lucas has much better control and command of the offering at this point."
On the type of hitter Riley can become:
"The higher levels will be more difficult, but I can see him hitting .280 while flirting with 30 home runs annually. He’ll open the 2016 season at Rome but projecting him to continue to rise at his current rate is not realistic. Still, he’s an exciting a young hitter as the Braves have had in a long, long time."
On Olivera's impact next year:
"I believe he will have a significant impact in the lineup and play solid defense, at least for the next two or three years. I don’t see huge power numbers for him but he is definitely the best third baseman the Braves have had since Chipper was in his prime."
On Mauricio Cabrera and his control problems:
"That’s the million dollar question. Cabrera’s arm strength has gotten stronger of late,
topping out at 104 mph during instructional league."
On potential Aces in the Braves system (keep in mind his definition of "Ace" meant there were only 10 in 2015):
"There are so few true number one guys in the big leagues. In 2015, for example, there were no more than 10 true number one guys. With that said, Allard and Toussaint have the raw ability that many aces tend to possess. Fried, Soroka and Sims aren’t far behind and could be at worst outstanding number twos if they continue to develop. Rarely do we see a situation like the current Mets with deGrom, Syndergaard and Harvey and even Matz, but the Braves’ guys have the same type of potential. Granted, potential does not always lead to reality, but it is an intriguing situation."
On Mallex and Albies hitting at the top of the order:
"An Albies and Mallex Smith in the same lineup would give the Braves their best one-two punch in terms of speed since possibly Otis Nixon and Deion Sanders, only Smith and Albies could prove to be better all-around players over the long haul. I know that’s a bold prediction but that’s the type of talent the Braves have headed toward Atlanta."
