They need to make it clear to the players. To the public, not so much. In fact, privacy laws may restrict exactly what can be said.
They have a responsibility to inform the students, which they did not do. And they have an obligation to inform the community at the very least that they took the scholarships away from ten scholarship athletes, and why they did so. This is, after all, a public university and the scholarships mostly come from public tax dollars. And let's be clear that this is extraordinary. So the university community and the state deserve an accounting.
Clearly, there has been no public accounting, and the administration have refused to explain themselves. So the administration won't give an honest answer to the student athletes, to the university community, or to the public.
That stinks. I'm guessing that there could be a lawsuit here to at the very least get to the truth. And the NCAA might also like to get a straight answer out of them, especially when the NCAA has approved the offering of four-year scholarships by a number of top conferences. This gives the game a big bruised eye.
