If Gardner runs sub 4.35, I'd consider him at 4. I'd prefer the EDGE rusher, but I'd consider a truly elite CB prospect (depending on how free agency goes).
Agreed. Part of my disdain for CB at 4/10 was that I didn't think any of the CBs were elite prospects. I'd be lying if I did a ton of research, but Stingley was considered CB1 by most for a while, even though he's been in-and-out of the lineup for 2 years now. And the fact there is a lot of debate as to which CBs are the best tells me there isn't one guy considered a can't-miss. I also think in this system, pass rush is way more important than cornerback.
Gardner is the one I can be convinced of the most. The guy was phenomenal in college and he has the size you're looking for. If he runs in the 4.3 range, then he will check every box of production, size, and athleticism.
