Forgetting the tutor herself since she has a whole mess of stuff that's complicated. This is what happened according to the NCAA.
1) There was a tutor that was doing classwork for 12 athletes across 3 sports, two of which were football players.
2) She was not instructed to do this by anyone in the administration (again, this is what the NCAA has determined). She just did it for the players.
3) Mizzou found out that this was happening and immediately fired the tutor, suspended the players, and reported the incident to the NCAA.
4) Mizzou admitted that the violations happened and fully cooperated with the investigation.
5) The NCAA confirmed that the tutor was not directed to do these assignments by anyone in the administration.
The football players are all no longer at the school, as is the tutor. Now, you might ask, what should the school have done in this situation to avoid the bowl ban plus major recruiting restrictions? Well the NCAA gave a very helpful piece of advice:
Mizzou should've lied to the NCAA and refused to work with them. That is actually the NCAA's recommendation.
