3) STEVE KERR

While Mark Jackson arguably instituted the identity of the current Warriors team, it was Steve Kerr who had established a dynasty of dominance within the franchise. Inheriting a team that had failed to prevail over the Clippers in the prior season, he had instantly steered the franchise to a championship. Paying close attention to player development, Kerr was instrumental in the success of Stephen Curry, Klay Thompson, Draymond Green and others. Further, his unselfish approach of stretching the floor paired with ball movement helped lure superstar talents in Kevin Durant and DeMarcus Cousins. Comprising a superstar starting lineup, they pose the threat of potentially sweeping teams en route to another championship.
