I can give you three names: Bell, Rogers, and Larry T.
2/3rds are owned by corporations and 1/3 by an individual.
I get your point though - sort of. I think you are confusing ownership with basketball executives in some case (Mickey Arison owns Miami, not Riley). You need big shots to win. I mean lets look at:
Pat Riley: he won his first championship with Miami after 11 years (yet the actual owner is Arison who won after 18 years).
Mark Cuban: he won his first championship with Dallas after 11 years of ownership.
Prokhorov: he won his first championship with Brooklyn/New Jersey after.... oh wait, nearly 4 years and nothing, well, a playoff appearance.
Jerry Buss: he won his first championship, well, immediately. It didn't hurt to have Magic and Kareem though.
Calm down, Brandon. TL has been on the job for just over 2 months and Ujiri for just over a month. As for patting himself on the back, TL had the history of Toronto thrown in his face when he first arrived when the man has not had a thing to do with it. It seems only fair he throw his own history back.
