I don't think it's an either or debate.
It's possible to recruit a CB with athletically ability in HS to play CB in college.
I don't think anyone has an issue with Curtis as an athlete, but he doesn't really project as a Corner on the next level. He has a pretty thin frame & physicality could/will be an issue for him at Corner, which would make him a project for a few years. At WR/KR/PR he can play immediately & make an impact.
Da'Quan Gonzales is an ATH that plays multiple positions, but is primarily a CB, a transition for him wouldn't take as long. Tyrell Raby is a WR/CB ATH too, but has the physicality & technique to go with good size where he projects easy as a CB on the next level.
There's no issue with recruiting athletes at CB, it comes down to the prospect, it's not a one size fits all situation. Every athlete doesn't fit at CB, some do more than others, among the ATH/WR/CB's we've offered Curtis is probably the last one that fits as a corner.
No problem with the take on my part, I like Curtis a lot, just don't see CB in his future. Hopefully it works out & the staff found a diamond in the rough to convert to CB.
