On your commit question: Any commitment by you to a college or a college to you before you sign a National Letter of Intent (on Signing Day your senior year) is just a 'verbal' commitment. And a verbal commitment is just a handshake deal...i.e. non-binding and backed only by good faith on both sides.
'Early' commits are just verbals. And in these cases the athlete initiates all contact with the coaches because the coaches cannot initiate or even call them back until after the athletes junior year.
