These are good centers. I would like any of them.
Only issue for me would be where do they go. Because if you're taking one of them, you're leaving someone else. There does appear to be a sort of premium in terms of where these guys are slotted to go.
I certainly would rather have any of these guys to say, an Okwara or Weaver or other destined to be 3rd string DE/DT.
There also is a very real issue of just how valuable is a great center? They aren't particularly hard to find in day 2 of virtually any draft. Really, I don't think Britt as a borderline PB center is any less effective than those that make annual PBs. I certainly wouldn't want to Chris Spencer our draft because we 'have to have' a top tier center.
And it's worth noting, that taking an OC in the top 64, probably means missing out on some really good WR talent. Guys that could/should produce straight away with some degree of expectation that they turn into a Lockett type value in a year. There is a genuine cost to taking one of these guys and for certain it's drafting into a position that is both fungible and routinely able to develop acceptable quality.
If we aren't overdrafting these guys (top half of R2), I'm ok with it. I do believe that we would be better off dipping into the OT market at end of R2 if it's not totally picked over. Because those types of prospects are harder to find. And cost a lot more to retain. You can't really get a decent OT for under 10M a year.
It's not the most efficient allocation of draft capital. Particularly when we should expect quality players at other more impactful spots to be on the board.
I'll be honest though, I'd be tickled to come away with Cushenberry at the end of R2.
