There are three points of view going on here, the fans, the players and the coaches. From the fans and players point of view the last 8 minutes were torturous. But the coaches wanted to observe/develop something. So the last eight minutes the coaches had the stall offense.
They are trying to see if any of the three, JL, RB or SN can play the role Kemba did last season if the game is on the line. So they had all three take turns at that role for the last eight minutes.
This is the difference between JC and staff and other coaches in college bb. They are not just about the win or beauty contests, they are also about development. I'll take the ugly last eight minutes knowing it will give the coaches and players something to work on in practice and increase the odds of going far in the NCAA's.
