I don't think they've proven they can recruit and develop elite OL yet, though I'm hoping the young guys show out next year. They've definitely proven they can scheme with any offensive personnel though.
Regardless of how good Bama OL was, would Campbell or Spraggins start there? I'm not saying 100% the answer is no, but it's not certain they would. And if they're not at least as good or better than what you and
@JacketVol say was a bad Bama OL, then that unit isn't ready to be a championship level unit, unless the young guys HAVE developed and are now ready to be that level.
I'm not saying for sure either way, but I think there's reason to be worried, since our main hope is that unproven young guys prove themselves.
