Not true.
Here's a closer representation of the truth.
The kid got recruited down from Jersey to run a high powered offense at IMG. He was 16 when they recruited him and barely 17 when he got to IMG. The kid had some culture shock and become very home sick. It affected his on-field performance. He wanted to be closer to home. He and UM parted ways in favor of him signing with his home market team, Rutgers.
The kid is still a very talented QB. Hearing that he is being announced as the game 1 starter as a true freshman is indicative of his talent level.
You are absolutely correct in your assessment that there is no reason to hate on the kid. He bit off more than he can chew as a 17 year old kid and is now settling into a more comfortable situation. Best of luck to him.
