Ashton Carter for AT&L? Really?

This was surprising. Ashton Carter, I thought, was a "nukes and strategy" guy. AT&L, as I discussed with my friend "Abu Comptroller" yesterday, is the job where it pays to a) know the acquisitions process inside and out and b) be prepared to be a real jerk to everyone. "You're certainly not going to win Prom Queen in that job," Abu Comptroller said. Here's Carter's bio. Here's his predecessor's. Compare. Does this not seem like an awkward fit?
