If they see Vann as a SDE, and not a pass rusher, I would agree that there is no need to get him at this point.
1 per year is ideal depth, but, IMO, taking 4 in 1 year, and skipping the next 3 years doesn't get you to the same place. It's not just about having depth, but also experience. Similar issue, but not as extreme, when you take 0,0,2,1.
1. Last year at Wake, Elko's best pass rusher was his SDE. Huge misconception is that the WDE is your "pass rusher", and it isn't always the case. We need pass rushers, but that could come from WDE, SDE, Buck, Rover, etc. In fact, to take it even further, last year at Wake, Elko's Rover had more TFL's and sacks, than his WDE.
2. On your last comment, that's not even close to what is happening, so I'm not sure why you are concerned by that. They signed 2 in 16' and 1 in 17'. So they are on track from a numbers perspective. Again, if we sign one at both positions, that will be 4 deep at both positions to start the 2018 season. 2 juniors, 1 sophomore, and 1 Freshman, that's good numbers. Can't change what happened in the past.
3. Plus, you don't fix the problem by loading up more in one class. It's about balance and you have to start to build out balance at some point. He started with LB last cycle, and it looks like DE might be this cycle. While focusing on getting numbers at DB
