My point wasn't that scarcity = value. The value in DT over end is that historically offenses with elite QBs have been able to gameplan around edge pressure easier than interior pressure. Even Payton and Brady were not immune to this so when you get to postseason it can still wreck gameplams. With ends you can chip with tight ends, use misdirection, hot reads, get the ball out quick, etc... harder to do all that with interior pressure when you have a guy that can get pressure even with double teams.
