Per usual, your lists often read like a 7 year olds Xmas wish list. Not much ND can do about those guys not being interested. We recruited the heck out of the one that was, Ossai, and he simply will not leave Texas. We offered 25 DE prospects, per 247, and actively recruited approx. a dozen of them. None were interested.
I don't believe we have a "numbers" shortage at "pass rusher". It's 6 players for 2 spots or a 3 deep, depending on how view Justin A. All have at least 2 years of eligibility.
Prior to the exit of MacCollister, the staff viewed another DE as a luxury, and rightfully so, numbers weren't a need so they went after the "big fish", that had interest, that being key here. They recruited quite a few players early, Ossai, Smith, Ojulari, Chatfield, McClain, Oweh, etc. Then they even went after Enagbare and Langham later in the cycle, but, again, not much interest. Nothing you can do there besides recruit them.
Similar to your posts on DB recruiting, which turned out to not be a big deal, I'm assuming this will be the same.
