Absolutely no reason to leave as of now. Another year to train under Lashlee and he'll make big money in 2 major markets. He's from Houston and he'll ball in Miami.
Why would King leave? Take two years to build your resume. Be the face of the program in a huge market and make money off your likeness as well.
Theres absolutely no rush imo. To be a fringe QB in the NFL? Nope, stay and build your legacy kid!
