This puzzle might have been a little too proud of itself for the fact that the (25A: Minimum number of times each letter of the alphabet appears in this puzzle's solution) was FOUR. It allowed for easy guessing of exotically-lettered words like KUMQUATS for (38D: Orange fruits), and TAZO for (60A: Tea brand owned by Starbucks).

And QTRS are really more accurately NFL game divs., not (12D: N.F.L. divs.).

Huh.
Not terribly satisfying.
