What would you say if you were him?
I'd probably go full scale Bruce Weber melt down. Blame the players and say "I'm going to the Cheesecake Factory to get a scotch."
Or
I'd probably start with an acknowledgement that the wheels came off the second half and that I (and my staff) have got to do a better job of getting the players back on track. I'd also add that its my responsibility to call plays to put us in a position to get easier shots.
"Look, I'm frustrated. I don't like losing, those men in the locker room don't like losing. We're going to battle these next few games and try to get better everyday. We're going to start building towards making a run at the BTT title and put our self in a great place, not a good place, but a great place, heading into next season."
That's the best i could come up with after 30 minutes, maybe he should have started working on his draft during half time because nothing else he did seemed to matter.
