The lead official, Ken Mauer, can be good or bad depending on the game. Mauer is known to carry grudges and often calls games with an agenda. He is quick to call technicals and one time he called 5 techs in 10 seconds in a Wolves game. However, he is more likely to let them play rather than call a lot of ticky tack fouls. His home W/L record this season was 35-29. The Celtics are 6-4 in their last 10 games with Mauer while the Bucks are 5-5 in their last 10.
Kane Fitzgerald - Fitzgerald has been involved in some bad officiating in the past. As with all refs, though, he can be good or bad depending on the game. As with Mauer, he is quick to give technicals. He is the only referee to ever eject LeBron from a game. He gave KG a very quick pair of technicals (from about 30 feet away) and tossed him in the 2nd quarter a Celtics game vs the Knicks. His quickness in giving technicals dates back to his days in the D-league where he was close to the top in calling technical fouls there as well. Players need to behave themselves when he is calling the game. His home W/L record this season is 46-24. Both teams are 7-3 in their last 10 games with Fitzgerald as a referee.
Tony Brown - Tony Brown has been both good and bad in the past in calling Celtics' games but mostly has been good or bad depending on the lead referee at the time. His home W/L record this season is 40-26. The Celtics are 8-2 in their last 10 games with Brown while the Bucks are 7-3 in their last 10.
