From what I'm gathering there's a possibility of 6 offensive linemen alone being brought in this cycle - Donaldson (starter material and our most important recruit), Slaton (close to starter), Hillery (red-shirt who'll likely see playing time in his 3rd year), Dykstra (same as Hillery), Gaynor (same as Hillery), and Herbert who just needs a red-shirt for S&C purposes.
I'm okay with that approach as you'd only need 2-3 linemen next cycle and we can phase other guys out whom are about to graduate or just were bad takes from previous cycles.
