Los Angeles was tabbed as the favorite by 46 percent of the GMs who responded. A big reason was Leonard, who not only ended LeBron James' streak as top small forward that dated to the 2005 poll, but was also voted the league's most impactful offseason addition, best defender and best perimeter defender.

Leonard proved what a difference he can make last season. He led the Toronto Raptors to their first championship in June, triggering celebrations all over Canada. He returned to play in front of the country's fans in the Clippers' preseason finale against the Dallas Mavericks in Vancouver, British Columbia.

"They should be excited," Clippers coach Doc Rivers said before the game. "He did something very special for this country. So that'll be a lot of fun for him, for sure."
