Caleb Barnett has already indicated to AL.com that he plans to come to UA.
Myles Upchurch seemingly tweeted implying the same thing, but that was before he was drafted in the 19th, so we'll see if that holds or if the Reds make a major run at hitting his "number."
The only guy really "up in the air" at this point, IMO, is Ma'Kale Holden. I can't find anything one way or the other what his thoughts are. Hopefully, he decides to bet on getting himself into a top draft pick, but if the Brewers offer up some outrageous money in the 20th, that could be hard to pass up.
My expectations are that everyone else will sign (Quick, Snell, Richie, Stieg).
