The Celtics are 73-60 all time with Foster while the Mavericks are 73-72 all time in games Foster calls. Foster is known as the Fixer and The Extender and is known for trying to keep games competitive as well as trying to extend series to extra games. He was voted the worst ref in the league in a poll taken of league referees (just ahead of Tony Brothers, who is in the replay center). Just the name Scott Foster tends to cause fear and gnashing of teeth by every fan base in the league. He can be very good but he can also be very bad. He has been good in the Celtics recent games. He called Game 4 of the Celtics sweep of Brooklyn in 2022.
