"We lost some games we thought we could win," Bryant said in a postgame interview. "This feels good.

"Bam is a big part of our team, but he can't play all 48 minutes. I just try to give some relief to our (starters)."

Jimmy Butler, who missed the previous game due to illness, returned and provided eight points and eight assists in 25 minutes.
