The stress began over a week ago as head coach Doug Marrone left Syracuse to become the Buffalo Bills new coach. More uncertainty surfaced days later for Allen as the Orangemen lost their second coach, offensive coordinator Nathaniel Hackett, who will be Marrone's offensive coordinator in Buffalo.
Without the two coaches who were primarily responsible for gaining Allen's commitment no longer on board, things turned complicated real fast for Allen. It was thought that the hiring of Coach Scott Shafer would be enough to secure Allen's commitment, but unfortunately for the Orangemen, TCU was in the background making a move.
The Frogs had recruited the 6-foot-3, 185-pound Allen throughout the year but backed off once learning of his solid commitment to Syracuse. Once the coaching change was made, Allen said the Frogs entered the picture once again. In a span of just over 24-hours, Allen received an offer from the Big 12 program and he visited the Ft. Worth campus and ultimately made the switch.
This is a great get for the Frog's, the class now stands at 16. TCU is expected to take somewhere between 20-22 at the end of the day.
