We have plenty of data and evidence that clearly shows he's not the guy.
BYU does not have the ability to consistently surround Kalani with enough babysitters to make sure the program runs smoothly.
So you can convince yourself that 6 wins is some sort of major accomplishment that makes Kalani deserve another year. Or you can take a step back, look at his entire body of work and state of the program, and easily realize that he doesn't have what it takes to run this program to its full potential.
