The article says he de-committed then re-opened his recruiting and chose MTSU over a couple other schools.
De-commitments can happen for lots of reason and can be initiated by either the school or the player. Sometimes one or both parties just realize it's not a good fit. Sometimes one side has buyer's remorse.
Without knowing who initiated the de-commitment or why, there's no point in trying to draw any conclusions either about him or the state of the program.
Perfect Game lists him as a mid-80's LHP. I have no idea how he projects.
