Given they were technically still in the race at that point, I can see why he'd get cold feet on trading Turner, though that would've been a great and much needed return.
Not selling high on Paxton and Kenley is inexcusable in retrospect. But again, I think he kind of was in a no-win position at the deadline. If he sold everyone when they were only about 2.5 or 3 games out at that point, they'd be killing him and the stands would've been emptied a month earlier. But given what's transpired since then, it obviously would've been the right thing to do.
