Colbert originally signed to play at Texas but injuries and changes to the coaching staff influenced his decision to go to Miami. The transition in schools also forced a transition from playing safety to cornerback. Colbert finished the 2016 season with 22 tackles, one interception, and three passes defended through seven games.
"That's one of the biggest question marks for Adrian Colbert going into the 2017 NFL Draft," wrote Russell Brown of FanSided back in January. "The injuries even date back to when he was a kid. At the age of 9, he was in a bicycle accident and spent more than a week in a coma. He then has the scars from surgery on a broken arm and meniscus tear in his knee. However, despite all that, he's still standing and playing strong. No doubt, he's one of the toughest guys on the gridiron."
Tony Pauline of Draft Analyst had the following to say in his scouting report:
"Colbert showed a lot of progress in his game last season before going down with injury and has the size and skill to line up in dime packages on Sundays."
