It is the inconsistency that gets to me. What is called one time, is not called the next. In some games the officiating changes so drastically from the first half to the second, I swear somebody give the refs a pep-talk at half time "You aren't blowing the whistles enough. You have those things around your neck for a reason. Use them!"
I think most teams can deal with a game called tightly or called in the "play on" mode as long as it is done consistently from the start of the game to the end, and the standard is applied equally to both teams. I can only imagine how frustrating it must be to go out for the second half and all of sudden what wasn't called in the first half is being called in the second.
Just like everyone else, there may be personality issues with coaches or performance competition among officials. It cannot be much different than any other working environment. In the case of Dennis DeMayo, his friendship with Geno may, on an subconcious level, lead him to give the other team more benefit of the doubt and UConn no such courtesy as a way to prove his friendship with Geno doesn't impact his officiating. In fact, that is exactly what is happening. I have seen Dennis do other games, and think, on the whole he is a very good ref. Just not when he does UConn games. He should move to another conference, or recuse himself from doing UConn games because he and Geno have such a long, friendly history.
