I think Anthony Smith becomes a DT. He is a pretty big dude already, but I echo your excitement about him. He moves really well.
My big ones are Knuth, Hoskins, and Kelly.
Knuth: He is just a higher caliber (as was Athan) QB recruit. He seems to have prototypical size, makeup. There is also the fact that everyone from South Dakota gushes about him. I know, they are likely as provincial as we are, I get it, but sometimes you just know.
Kelly: He is a 6'2" CB. Having that kind of size at CB (if they can cover), allows you to do a lot of things. If we find another star to play opposite Walley, watch out.
Hoskins: I realize he did the things he did against central MN kids. That said, he is electric. He is explosive, dynamic, seems like a natural pass catcher and he is legitimately fast.
