Both executives were named on 11 ballots from executives representing each of the 30 NBA teams, the NBA said Tuesday.
Forman, in his second year as general manager but 13th overall with the Bulls, helped put together the team that posted the best record in the NBA this season at 62-20. He installed Tom Thibodeau as head coach, and signed free agents Carlos Boozer, Ronnie Brewer and Kyle Korver, who meshed well with Derrick Rose, who won the NBA Most Valuable Player Award this season.
Riley, in his 16th season with the Heat, also had key free-agent signings -- LeBron James and Chris Bosh -- to join Dwyane Wade. Miami was 58-24 this season for the second-best record in the Eastern Conference.
