In my first post I initially included a #4 titled, "one way street." It was exactly what you wrote, that no way you can go to a team or individual and say "do your best ever and dominate." I decided to delete it when I seemed to be rambling aimlessly.

A fix has to be a tank, either a big favorite not to cover or some type of underdog to blow the game by more than the number. So that further limites the opportunities.

Exactly, college sports are more vulnerable. There have been numerous high profile college basketball shaving scandals, from CCNY in the '50s to Tulane and Arizona St and others more recently. This thread asked about pro sports so that's where I focused.
