Jaylen Brown was named NBA Finals Most Valuable Player on Monday as his Boston Celtics polished off the Dallas Mavericks four games to one to earn a record 18th championship.

"It was a full team effort," Brown said as he accepted the Finals MVP trophy named for Celtics legend Bill Russell.

The 27-year-old averaged 20.8 points, 5.4 rebounds and 5.0 assists in five Finals games and delivered a strong defensive effort against Dallas star Luka Doncic, the regular-season scoring leader.
