Fair enough, I think your list shows cause for very serious concern.
For starters, it's filled with kids that either A: Don't have high ceilings, in my view (Norwood, Sims, Campbell, Carter) or B: Can't get on the field now for a roster that while more talented than anything we've had in a while, is still so-so (Verdis Brown chief among them but also include Avery and Oladipo). You've also listed essentially every player we currently have with 2021 eligibility without mentioning the potential of losing some of these names to the transfer market. That market is a two way street. I think we lost 8 guys last year, does that sound right? We have to factor this in, especially for the QB room (If we do sign either Dixon or Spann or both, that room won't be big enough for everyone. Someone will likely transfer) but I guess my real concern above all else is simple: Your list above? It's only 20 names long. Our talent pool is so shallow, it leaves us far more susceptible to having a couple of injuries derail entire positional groups or even outright units. We're already hearing that complaint now. "Man, not having Bobby killed us. Not having Marquez killed us. Not having Betiku will kill us". That's not because we're short on numbers, we have guys to play in their absence. What we don't have are GOOD guys to play in their absence. If/when injuries occur we will be forced to throw far lesser talents out there and live with the results, however negative they may be, because we won't have any other choice. That's how your list reads to me.
Still see guys with real potential. One kid I see big things in store for that doesn't get much discussion here is Tariq Barnes, I think he's got a very bright future. It's just scary how short our list of names is.
EDIT: I excluded discussing offensive line for a specific reason, projecting them is extremely difficult if not impossible. For the offensive front, more than any other position in football, the recruiting analysis pre-college enrollment is not something I put a tremendous amount of stock into.
