"Since pulling out a symbolic Stanford tree and donning nerd glasses on National Signing Day in 2014, I have had the most amazing time of my life. I have grown and matured more than I ever could have imagined," Thomas stated in a release by the school. "I arrived at Stanford somewhat shy and uncertain; now I stand a curious, intelligent, dedicated, and motivated man who is ready to take on any challenge, including the NFL. With the support of my family, I have decided to forgo my last years of eligibility at Stanford and enter the 2017 NFL Draft."
