Usually if you graduate on time, don't you graduate in 4 years?
Spoken like someone that has never played a minute of University sports. Typically scholar athletes do not graduate in 4 years given that few if any will take full course loads during their playing season. 15 credits and 4-5 days of sports commitment are not conducive to achieving solid grades.
It used to be 3 - 4 courses during playing season. 4-5 second semester and maybe 1 course during the summer if you wanted to graduate in 4 years. Again, few if any did this. Typically it was a 4.5 to 5 year process.
