Actually, Russell was simply a coach for the Sacramento Kings early after their move from Kansas City, I believe, and he didn't fare very well there. Rudy T and Jerry Sloan are ex-All Stars who have been pretty good to great as coaches. K.C. Jones is a Hall-Of-Famer, but not really that good of coach in my opinion. And there's Lenny Wilkens.
But Magic, Isiah Thomas, and Dave Cowens were stars, but miserable failures as coaches.
Bird is the biggest name who had success, but many folks credit Rick Carlisle - Bird's top assistant - with that team's success.
And Nate McMillan, Rick Carlisle, Don Nelson, Avery Johnson and Terry Porter, Pat Riley, and Phil Jackson have been great coaches, yet all were pretty much just role-players at the NBA level.
