This was my main initial take as well. Given the recent tilt towards mid-level/higher floor college kids to fill holes at the upper levels of the system and the seemingly broader opinion that there's substantially more high-ceiling talent available this June than in the last couple of years, this would seem to be the opportune time to take a shot at a couple of bats IMO.
While I completely agree with those that subscribe to the BPA approach, I also think the guys in the War Room have to continually keep an eye on the total Organizational Tree as well. Following Gattis' promotion, we don't seem to have any real potential power bats that appear capable of ever becoming anything other than platoon guys (at best). We also don't seem to have a prototypical 3B in the system - while Kubitza has shown promise, he also profiles as more of a Chris Johnson "hitter" that doesn't seem to look like he'll develop typical corner power. The clock has finally begun ticking on Salcedo and even if his bat finally develops, it appears his defensive liabilities will wind up pushing him to an OF corner. Caratini is another "soft power" guy.
The main reason I singled out Davidson and more particularly Chavis is that they seem more capable of sticking as prototypical corner infielders than most players that would seem to be available in the range where our picks should fall. Assuming typical development curves, Davidson could slide to an OF corner if Freeman's extended rather than Heyward or J-Up, and Chavis could conceivably be ready by the time the organization no longer controls Johnson.
