I think the refs intentionally called fouls, etc, in a manner to get to a game 7 (let the Lakers win game 6). Whether they did this for their own reasons, for the league (whether overtly told to or just because, in general, the refs knew the NBA liked 7 game series for this or similar matchups), or as part of something else (mob/gambling, etc.) I don't know. But the game was rigged. That much is as plain as day.
