It happens all over and more than you think. Just look at Friends and see how many transfer in for 1 year to repeat a grade. That is the new hiding spot for GC parents.

It has been going on in all sports for a very long time. Red shirt freshmen in football and just look at the NBA draft. Look at the top ten taken. Not sure if their were any kids who graduated but they were all 23, 24 years old.
