From the video

I don't think Drew Aller is was a a strong pick at the range that they picked him... Every time you work on technique, you move slowly... your muscle memory has to absorb the information... you're reprogramming... he has done things a certain way and Mike McCarthy wants things done a different way

Poor draft capital; practice technique concerns overblown but value concern stands.
Bob Harris argues Aller was not a strong pick at the range where the Cowboys selected him. While practice video concerns about his movement and technique work are overblown—slow movement during technique drills is normal and reflects Mike McCarthy's reprogramming of his mechanics from his previous approach, requiring deliberate repetition to internalize new technique—the underlying draft capital concern remains valid. Harris notes that every time you work on technique, you move slowly because muscle memory must absorb information gradually, similar to how elite musicians master complex skills by playing slowly first.
