Miles or Crowton? Anyone know who called the last series?

Forgive me if I missed this in all the topics about the end of the Tennessee game, but seriously, what I want to know is who made the decision to:

(1) switch to Jefferson on 2d and goal to go from the 2 yard line after Lee led the team down the field to get in position to score;

(2) only had one play called (apparently) when Jefferson was sent in to run the option on 2d down; and

(3) substitute personnel with the clock running out after the option play came up short (not to mention the fact that Jefferson was standing away from center toward the side line (rather than getting under center) looking to the side lines with a "what the F do I do now" look?)

One can really question the wisdom/coaching aptitude of anyone who did any one of the above but most certainly numbers 2 and 3. Seems Miles is getting most of the heat but it seemed pretty obvious from Miles' post game press conference that both these decisions (2 and 3) were by Crowton and Miles was not happy with it especially the personnel changes (which, ironically, is what snatched a victory from defeat as the personnel changes is what led Tennessee to have too many men on the field so, wait, maybe that last decision was actually coaching genius after all - just kidding).

I am guessing it was Crowton and, sadly, is way too reminiscent of the Ole Miss game last year (not having a back up play called if the Hail Mary pass came up short but there was still time on the clock).
