I know there's a lot of opinions when news comes out like this, especially with him decommitting from an in-state school.
This young man's three main reasons for committing to IU were the Kelly School of Business, the strength & conditioning program (Dave Ballou and Dr. Rhea), and the DL Coach (Mark Hagen).
Since Rodney's commitment, Coach Hagen was named DL coach at Texas and Dave Ballou and Dr. Rhea both took jobs at Alabama. No one can blame those guys for making those moves that they deemed were best for them and their respective families.
Due to those changes, none of which he had control over, Rodney decided that Penn State was a better fit.
Imagine agreeing to take a new job with a new boss and a new location. Then between agreeing to take the job and starting your first day, the boss who you wanted to work for left and the location changed. You may (or may not) decide to now not take the job because the situation is different. That's all that happened here.
Completely understandable if you look at the situation through the lens of the student-athlete.
Coach Allen is absolutely top notch and Indiana is in great hands with him at the helm of the program. It was simply that the things that were most important to Rodney are now not the same.
