With apologies to both Rotary and Interact clubs everywhere, I have devised a simple four way test to determine if you have a good coach.
1-Do other schools want him?
Does your coach come up on list after list when a coaching availability comes up? If so, chances are you have a good coach.
2-Would you be pissed if someone else hired your coach?
Consider this a back-up for question number one, as on a rare occasion your coach might make a short list of someone else and you know he isn't qualified for the job.
A good test to prove how well you have it with your current coach is to judge how you would feel if he left. If you would be pissed, then you know you have a good coach.
3-Is he respected by his national peers?
Many coaches can luck out and win a Conference Coach of the Year. In fact, it is speculated that sometimes other coaches in the league will vote for your coach as Conference Coach of the Year just to keep him around for awhile longer(see Lavin, Steve).
The real test is if a national voting body selects your coach as a Coach of the Year, then you have yourself a terrific coach.
If you can answer yes to the three above questions, you are in good shape.
For question four, you want the answer to be no.
4-Do the rivals in your league plead for you to keep your coach?
Do they try to convince you in person to give your coach more time? Attempt to persuade you online that your coach is merely a victim of bad luck and not to be so hasty to fire your guy?
This might be the most damning of tests, as if fans of other teams in your conference want you to stay the course on YOUR site, and yet clown your guy on THEIR site, then you have a coach that sucks.
