Bob Myers steps down as Golden State Warriors president and general manager
Myers played a key role in the team winning four championships during his tenure since 2011
Myers' contract expires in late June, with Warriors owner Joe Lacob unsure of his replacement
Executive VP of basketball operations Kirk Lacob and VP of basketball operations Mike Dunleavy Jr. are possible successors
Previously reported friction regarding salary and 'two-timeline plan' played a role in Myers' decision
Myers' departure might affect the future of players like Draymond Green, Klay Thompson, Jonathan Kuminga, and coach Steve Kerr
