"I feel very blessed. It's a dream come true," Dean said. "I've been dreaming about this since I was a little kid so I'm very happy and ready to get to work. A lot of schools recruited me heavily but Arkansas was my top priority, number one."

"Daytrieon's hard work and dedication is what we look for in future Razorbacks," Bielema said. "We're exciting to welcome him to the Razorback family and have him join us next spring to maximize his potential. Daytrieon Dean, Ty Storey, and Zach Rogers as the the start of a very special 2015 signing class. He continues to display the core values of what our program is built upon academically, athletically and socially.
