He seems to have really liked Coach Kruger, so perhaps it was just a reaction to news of his retirement. It's possible the new coach could have swayed him to stay. But yeah, much easier to handle him going pro than transferring to another program. That would have been tough to take.
But in one of my early posts following Lon's announcement, I warned that we were at risk of a slide, and this is the kind of thing I was referring to. We've lost Harmon (for now, at least), we've lost Austin (though there was no assurance he was returning), and who knows who else might move on when we have our new coach. We've got to hang on to Cortes and, especially, Noland, and it would be great to have Williams and Manek back too.
