He didn't end up making it to MU because he was advised poorly and didn't take all the required core classes. So when his GPA and SAT scores came back and were fine, it still didn't matter because he didn't have the core classes and had to go to JUCO. Ended up at Indiana eventually, so there was nothing wrong with him from an intelligence standpoint.
Luckily it sounds like Guess was able to recover from not being advised well early on.
