College basketball is fine, we do this every year. It will never surpass the NBA and people will always start paying attention when March Madness rolls around. As long as people have alma maters that they care about they will watch the sport to some extent.
Asking Coach K about the state of college basketball in general is stupid. He has no idea what the state of the sport as a whole is because he sits on a golden throne surrounded by 5 star one and dones. He's also senile so his opinion is useless to me.
With increasing salaries, continuously improving facilities for even the mid-major schools, growing TV revenue, and ease of recruiting with improved technology and means of networking I would think most coaches are content with where the sport currently is even if they won't say so because they have some sort of agenda to push.
If the recruiting scandals are enough to turn you off from the sport for some sort of "purity" reason then you probably should stop watching sports in general because, wait for it, people cheat on every level and more frequently than most people would guess. College basketball is just fine and will continue to be.
