What is Chip Graber's role in the plot of Last Shot: A Final Four Mystery?

Chip Graber is the star player for Minnesota State University (MSU). Chip is also the target of the blackmailing scheme. Chip is not only the star player for MSU, but Chip's father is also the head coach of the basketball team for MSU. Chip's ineligibility not only puts the Final Four games in jeopardy, but it would call in to question all of the games that MSU won.
