Professional career

It also was the fourth-fastest recorded time for an offensive lineman at the combine since 2006, trailing only Eagles' Lane Johnson (4.72), Saints' Terron Armstead (4.71) and Vikings teammate Aviante Collins (4.77). He also had the best time among offensive linemen in the three-cone drill, at 7.14 seconds.
