Yes, the defense played poorly, but the offense didn't help last night especially at the end of the first half.
I think the offense at the end of the first half basically gave the game to Memphis. Score was 21-21 and the defense held on 4th down and UConn got the ball with 4:13 remaining in the half. UConn's offense proceeded to have a 3 and out and only ran 1:05 off the clock giving the ball back to Memphis with 3:08 remaining in the half. More time should have been run off the clock and sometimes the hurry up offense needs to slow down to speed up the clock. Memphis scored and made it 28-21. UConn got the ball back with 1:47 to go and UConn's offense fumbled on their 34 yard line and gave Memphis the ball back on UConn's 35 with 1:35 remaining. Memphis scored making it 35-21 and the game was basically over.
At worst, UConn should have been down 28-21 at half time, instead they were down 35-24 and the momentum had clearly flipped in favor of Memphis.
And, look at the time of possession: Memphis 36:50, UConn 23:10. I'm not defending Crocker and his scheme, but no defense is going to hold up playing against a hurry up offense that has the ball that much. The offense has to step up and take more control of the game and there are times that the offense needs to slow down to help the defense.
