When it comes to NFL Draft preparation, experts love to point to specific skills/tangibles to help relate that into success in the NFL. For instance, when evaluating quarterbacks everyone loves to point to not just height, but hand size as a trait which can lead to success, or failure. With pass rushers hip flexibility and ‘bend’ is a trait which shows up in the three-cone drill and can show a direct correlation for success on the gridiron.
When it comes to defensive backs, not only is height something which many view as critical, but arm length, or wingspan, is also important so defenders can get their hands and arms involved to break up passes.
