Truly, Smelly, do you really think there's no review of Big 10 hoops officials in place? Unless things have drastically changed in the past 7-8 yrs, I can attest that every court official, every game, is evaluated on every possession. In the Big 10 as recently as a decade ago, each official even submitted an evaluation of both partners for every game! (Again, unless it's changed) there's both an in-person appraisal and a supervisor's video evaluation after every game. As NU Houston describes, there are consequences -- particularly for conference tournament and post-season assignments -- for negative evaluations. I personally know two officials who were end-of-season "de-listed" (fired) for overall sub-standard performance. Objective appraisal is a continuous process.
Another thing: with rare exceptions there's no such thing as a Big 10-only basketball official. Most are on rosters for at least 2-3 different conferences (different from football, for instance). So an official working Big 10 one night have a Big 12 or Atlantic 10 assignment a night or two later. Harangues seen here over "Big 10 officiating" are misguided; if officials are lousy (as prized poster Lunker, for instance, consistently contends), they're equally lousy everywhere. (Two men's basketball coaches in the Big 12 this season have recently been tossed from games a-la-Collins for demonstrations against their conference's officiating.)
I called basketball (and two other sports) for 30 years and never even approached a D-1 level of ball. Never tried. But I was a member of NASO (National Association of Sports Officials) and attended a number of its annual conventions. It was interesting and satisfying to be around top officials of all sports, basketball included. Virtually without exception they were Grade A people, committed to striving for excellence in their sport and other aspects of life.
Isolated calls or no-calls can and will always be questioned, particularly given the video scrutiny to which so many games are subject now. But I implore anyone to think very carefully before questioning an official's integrity or accusing one of pre-existing bias.
I apologize if the preceding screed has been tedious to read, but I was obviously moved to respond to remarks made on this board and of course in many other places.
