A couple of surprises, and the positions on D that i believe need to be upgraded and ways to fix them

Elite pass rushers can do that, but that's why they're elite. What about the rest? There are very few elite pass rushers. In a group of 10 good pass rushers, how do you rank them? Just by sacks?

If you have 2 elite pass rushers, 1 with more sacks but fewer forced fumbles and 1 with fewer sacks but more forced fumbles, which would you call the better pass rusher?

I'd call the player with more sacks the better pass rusher, and the guy with more forced fumbles the better playmaker. As far as overall player, you'd have to look at their entire body of work.

If your argument was "you can't rate a DE strictly off of sacks", then I'd agree with you wholeheartedly. But the argument is that "sacks are not the best measurement of a _pass rusher_", which is unequivocally wrong.
