A commitment to OU was probably expected by many the day that 3-Star 2016 WR Zach Farrar (6-3/210) picked up a Sooner offer, but he made his commitment official just a few moments ago with the following tweet.
Farrar is a prototypical outside receiver, who possesses the size to be a difference maker at the next level. He starred for Southlake Carrol High School in Southlake, TX. Farrar is currently the only wide receiver commit for the Sooners class of 2016 (Ryan Parker's situation is up the air because of grade concerns).
I would look for the Sooners to add an additional wide receiver between now and National Signing Day.
