First, I do not blame losses on refs. Almost 99% of the time you still control the outcome as a team, even with bad calls.
That said, the worst thing to happen was the officials calling a string of contact fouls on CU. The foul total was 8 to 1 in favor of us by the 14 minute mark. Foul totals tend to even out, not because officials do things intentionally, but officials are human. They see those foul totals and change the way they call the game. I really thought at times we still did a good job of attacking the rim after that, but a lot of body contact fouls just weren't called. By the 5 minute mark or so the foul totals were 9-8. Now, CU did a good job of forcing us to change some shots and we just missed some, but I find it hard to believe a team can foul 8 times the first 6 minutes of a half, and then go nearly 10 minutes with just 1 foul call. Overall the officials were just very inconsistent, but that is not a surprise.
It was crazy in person watching how differently each game was called by each different officiating crew. At times it was almost like each crew had a different set of rules on what constitutes a foul.
And one final point on my officiating rant to be fair; the "steal" by Pullen and pass to Sprads for a lay-up was one of the worst non calls of the game, and one of the worst in the open court all year. That was a play Mike Anderson would be proud of though.
