In Andy Katz's 3-Point Shot today, his first note takes another look at the officiating in last Thursday night's controversial Colorado - Arizona match-up.

Colorado coach Tad Boyle did follow up with Ed Rush, the Pac-12 coordinator of basketball officials, after last Thursday's controversial overtime victory for Arizona. Rush publicly defended the officials' call on overturning Sabatino Chen's 3-pointer at the buzzer. Rush did the same thing privately to Boyle. But Boyle said Rush admitted the officials didn't get a substitution call correct with under two minutes to go in the game. Arizona was allowed to sub in but Colorado wasn't, according to Boyle. That allowed a mismatch with Josh Scott on Solomon Hill, who ended up making a 3-pointer to cut CU's lead to five with 1 minute, 41 seconds remaining in regulation. Boyle said there was no hangover for the Buffs when they lost two days later at Arizona State. But he said this week's homestand should provide a great atmosphere, with USC and UCLA coming to Boulder. CU needs these wins to be a contender.

It's interesting to think about and frustrating that the Pac-12 officials miss these calls and continue to live up to their reputation, but Katz's last point is the most important; Colorado needs to take care of business at home this week to keep this season on track.
