While I don't place the blame squarely on KO for last night, he was not an "elite coach". They held Temple to 22% from the field for 15 minutes of that 2nd half and only managed a 12pt lead. A true elite coach would have had that game out of reach before his players could have fallen apart like they did.
If you do your math, you'll find that holding a team that's shooting 3s primarily to 22% rather than their normal 40-42% over 14 minutes is going to give you a 10-12 point bump. They went from down 2 to up 12.
I see your emphasis here is on UConn's offense
To start the second half, they scored on 6 of 7 trips. Good for 12 points.
During the Purvis missed layup sequence (ie Purvis missed layups on 2 separate trips), they went 1 for 3.
This all happened 7 minutes into the game.
If Purvis hits 2 easy layups (how can you blame this on Ollie?) then they go 9 of 10 trips for scores, for a total of 18 points to Temple's 5.
In other words, the offense is not sputtering for most of the 3rd qtr. of the game. It did score on 7 of 10 trips, and it should have bee 9 of 10 trips with 2 easy layups made.
What happens after that?
1. Missed DHam 3 pointer
2. 2 Miller free throws made
3. Brimah dunk
4. Miller missed 3
5. Omar Calhoun offensive foul on drive
6. DHam 3 pointer made
7. Gibbs 2 free throws made.
8. Non-call on Sterling Gibbs drive to basket
9. Sterling Gibbs offensive foul
10. Rodney misses a wide open 3 that goes in and out.
That takes them to 5:40 minutes left when Temple hits 4 three pointers in a row.
So, we are talking about a sequence from 12 minutes left in the half to 6 minutes in which they went 4-10 on offensive trips.
So, until the meltdown, the offense went a total of 11 for 20 trips total.
Those stats included 2 trips with missed layups by Purvis, 2 offensive fouls (one deserved on Calhoun, the other a question on Gibbs), 2 non-calls on Gibbs's drives to the basket, a missed Brimah dunk/fumble, and 2 missed 3s (one of which, Rodney's, was wide open).
How anyone can blame Ollie for offensive inefficiency up to the 15th minute of the second half is beyond me.
An easy argument can be made that they were highly efficient if not for the absurd and inexplicable. Purvis hits two layups, Brimah makes an easy dunk, Gibbs picks up at least one of the foul calls on drives, and then doesn't lose his head with some weird offensive foul I've never seen before, and we are talking about going 16 for 20 trips up until the 15th minute. That's not efficiency? I am not saying Adams should not be running the offense. But I am saying that he wouldn't have done any better for the first 15 minutes of the half. Which is what you seem to be saying in your post above.
Do you want Ollie to make the layups and dunks for these kids?
