Steve Kerr, who last season became the first rookie head coach in 33 years to win an NBA title, has quickly transformed a Golden State Warriors team that was once a laughingstock into one that could dominate for years to come. Players on the Warriors' roster have bought into Kerr's system and as a result set a single-season record by earning their 73rd victory on the final day of the NBA's 82-game regular season on Wednesday. Kerr, a 50-year-old former NBA player who was born in Beirut and spent much of his childhood in Lebanon, might never have enjoyed such early success as a coach had he not reconsidered an interview request from the Warriors.
