Donaldson and Reed pass the "gradma test", where even your grandmother who knows nothing about football can see they're so freaky they are in a class by themselves. As long as they keep their weight down, those two are made for this game and will be playing on Sundays. J Campbell is a close third there. Scaife is a step below that, but his HUDL highlights were insanely good, and he backed that up with outstanding play in the AA game. St Louis' and Mahoney's HUDLs were nearly as impressive. Of all our current OL, those were the 6 I knew would be in the two-deep as true freshmen. We recruited really, really well last class with Campbell, Reed and Scaife.
But to OP's original thread, you got an AH-developed kid like Herbert who has been here an extra year, and you just expect him to hold off the freshmen at least through camp. And Hillery was Scout MVP. It really is unexpected they've been passed up so quickly. I think it's a fair question to ask if that means the second-year kids are underperforming expectations, or the new guys are overperforming already-high expectations. From what D$ writes, I'm going to infer it's a little bit of both in that Herbert (especially hampered by injury) and Hillery need more time while the '18 kids are just that good.
