I hope this will be seen as a related question, and not a hijack...do the players usually get the same amount each year? Or put another way, how often does that amount get changed after the first year? I mean, can a player safely assume that if he starts with a 43 percenter that he will keep it all 4 years?
I thought of that question due to the reference to academic scholarships, which may be 4 year with objective/specific criteria to maintain at the original level.
