There's only a predictable effect if you know what part is rigged. Normally bettors who have an "edge" don't just pick a team outright, they engage in point shaving or other assorted fuckery and don't make their large bets until the last minute. It's not going to be a referee being obvious, it's going to be a bought off official handing out a cheap penalty given late in the game to bring the score from 2 goals to one when the spread is 1.5.
