I am a teacher/coach and I can tell you that grade changing happens everywhere and every year. If anyone tells you that it does NOT, they are misinformed, naive or just out right lying.
It is NOT always, or even usually, for athletes. It happens for an abundance of reasons; some are good reasons, some are bad and some are neither.
It ain't news worthy if it does NOT happen at Hoover or if some big name recruit is not involved.
Teachers help kids out for many reasons. The smart teacher does it before grades are posted and nothing is ever said. For example; there is a hard working young person that needs and 'A' to get a scholarship (not athletic); the teacher might help the kid out with a point or two on an assignment or two.
This is another case of athletes being held to different and higher standards. We should all remember that half of the doctors and lawyers in this country graduated at the bottom of their med/law school.
Again, let me state; the vast majority of grade changing that goes on is for non-athletic reasons.
Hoover City Schools is just a lightening rod for this issue. It's a shame that they have to spend their money on this crap because the world is watching.
