Many exceptions to these statements.
Not giving increases for good performances does not make you an ass. There has to be money available to start with, plus, giving too much money for increases preempts you from signing other athletes to provide more depth. It also says alot about the character of the athlete if they have to transfer schools because they all of sudden think they are "worth" more money.
Also, most coaches don't get jack shit for good performances. What a stupid comment to make. This is college track and cross country. Some of the athletes make more than the coaches with their scholarships. Typically, coaches sign one-year contracts, and get a 3-4% increase every year.
And you are saying it is likely that a dedicated athlete who improves should expect more cash, or else be disinterested?
Your post adds to the greed of college athletes and their parents, who are always looking for more money.
