I'm pretty pro-analytics, but this guy is talking in a vacuum about historical draft value without any reference to what resources were available in this particular draft. Would it have been great if a top-tier, flawless edge was available at 6? Hell yeah! But no defensive player went until 15 for a reason. Understandably, this may be difficult to encapsulate in statistics... but then it's your job to call out the potential flaws and drawbacks from your approach, not double-down with criticism.
