Steve Kerr sets NBA record for most victories by a first-year head coach

With the Warriors' 123-110 win over the Mavericks on Saturday, Steve Kerr became the winningest rookie coach in NBA history.

Golden State now boasts a 63-13 record and clinched home-court advantage throughout the playoffs with Saturday's victory in Dallas.

Kerr's 63rd win bests the previous record of 62 wins, shared by Bulls head coach Tom Thibodeau in 2010-11 and the Suns' Paul Westphal in 1992-93 season.
