Rule
The NCAA make the rules,don't play the drscrimWhat I'm saying is that is a discriminatory rule. Players who played that year are given 5 years of eligibility (if they want them) while players who didn't because of injury or something similar get only four. I believe a rule like that is challengeable and that challenge could win.
People make rules (often in haste). Those rules are frequently challenged, sometimes successfully and amended; sometimes they're just interpreted on a case by case basis. This is how some lawyers make a very good living.
Now, if someone can point me to evidence showing where this rule has been challenged and that challenge lost, maybe I'll close my mind on the subject.
