school for 4 years, had missed almost all of a season due to injury, redshirted another year, and wasn't allowed to play in their 5th year out of high school? It's not common like you claim. Having it be your 6th year out of high school, and having redshirted (non-injury) for one year and then missed another year due to injury is very common, and in that case you won't get the extra year, but that's not what is happening here.
