I'm not understanding your comment - you mean the ref was depressed because he bet on the wrong team?
I agree with this.
Here is my assessment of the referee categories.
1. Very good ref. Get's calls right almost all the time.
2. Decent ref, but makes too many mistakes
3. Simply a poor referee, also has a bias in favor of some teams
4. A crooked referee on the take
The refs good enough to be in (1) are in the NBA. I believe most college officials fall into (2) and (3). I assume there are a few in (4). I pray they get caught and severely punished.
There is one more category many believe in but I do not.
5. Crooked referees taking instructions from TV or the conference as to who should win.
There would have to be too many people involved for that to be kept a secret. I don't think it's happening.
