Even though it is not a well-known outside of Georgia, Kennesaw State is a rising university in the area. They've improved their offerings, their grad programs and are trying to transition from their roots as a commuter school. They've built housing but like other younger universities, they view sports as a way to get more students excited about the school. Think of how much attention Georgia State received during this year's NCAA Tournament. The leaders at Kennesaw want that same exposure. They've already invested in football. Now it is time for basketball. Once they demoted their most recent coach, it only made sense to go after an established coach. Skinner won't sell tickets, but he will win there and that is the end game.
As for why Skinner would take this job...some times it is as simple as it is the only offer to come his way. Skinner has interviewed multiple times over the years and never gotten that second chance. His (unfair) reputation and now his age probably hurt his chances at most major jobs and the mid majors in the northeast. Kennesaw offers one last chance to do what he wants to do: coach. The salary won't be huge, but it will be more than he is making at Bryant. With Al's eye for talent and his easy to install system, he can be one of the top teams in the Atlantic Sun annually.
I hope the two sides can come to an agreement. It could be a happy ending for both.
