The Jazz were beaten 104-88 at the Brooklyn Nets last night, leaving them without a win in the 2013-14 NBA season.
The head coach told reporters: "Losing hurts. It should hurt. It's four straight losses in the first four straight games. Nobody is going to feel sorry for us.
"We have to come to fight and keep working and try to get better and win a game too and feel better about ourselves."
Utah face fellow winless side the Boston Celtics later today.
