Most students take closer to 5 years than 4 in order to complete a degree. So, why not give athletes 5 years of eligibility with no redshirt season? Then, if a guy loses a year to injury, simply grant an extra season of eligibility. I don't understand why a guy is on a team, on scholarship, but not allowed to play. Or, if a team has injuries and needs to play a guy on a very limited basis, why it should cost someone a full year of eligibility. It seems like a waste of resources and talent that is neither good for the programs or the players. Stupid ass rule.
