Three years ago, the Dallas Cowboys selected Mississippi State quarterback Dak Prescott with the 135th pick in the 2016 NFL draft.
Fast forward to 2019 and Prescott has led the Cowboys to a 22-16 record and two playoff appearances.
In a video shared by Oklahoma Football's Twitter account, Prescott shared an uplifting message to last season's Heisman winner Kyler Murray.
"Trust me, I know what it's like to be doubted," Prescott said in the video. "Remember though, doubt is a gift. It takes you to the next level. So what if they doubt you? They doubted me too.
