If the plays are dissected carefully, then the person involved shouldn't matter a whole lot. For example, a "flagrant foul" instead of a "common foul" may be a possibility if one does a "wind up" (pull back and then forward) of their arm(s) before a facial hit. If there's a disagreement about what constitutes a wind-up, then other wind-ups on other videos are analyzed and a mutual agreement hopefully appears about whether a specific case matches the agreed-upon working rule(s). Perhaps the actual calls from the other game videos are used as a reference, such as whether a mere hint of wind-up is enough to score as such, or if the pull-back has to be very clear. Since different refs may have diff interpretations, perhaps the ref's history should be used as a guide. After all, the key question is about whether a specific game or season is "fixed", not all games from a given ref. If a ref has say 3 years of requiring mostly clear wind-up motions, and they were consistent on this during the target game, it probably wouldn't be considered an oddity. Sure, that's a lot of digging and a lot of work, but if a play-off conspiracy has potential merit, it's worth it.
