In Game Six of the 1998 NBA Finals, Michael Jordan led a comeback in the final minute that won the game and the championship for Chicago. There were two big incorrect calls involving shot clock violations during the game that would have completely changed the game, causing a five point swing in Utah’s favor.
The first is the most blatant, where the ref takes away a 3-pointer from the Jazz that was obviously shot before the buzzer. The second is closer, but still incorrect. A Bulls player gets a shot off right after the clock expires and makes it. The refs call no violation. Replay shows it was clearly the wrong call.
This commentary on this video is in Spanish, but the evidence is all there.
