Really what we're describing here is developing depth.
But just to say it again - Frost has not lacked in the "recruiting talent" category. For anybody who disagrees with that, get on 247sports right now and look at how Turner Corcoran, Bryce Benhart, Teddy Prochazka, Ezra Miller, and others grade out. We're talking about 4 star athletes.
But, how many of those guys are sophomores or younger? The issue I think really is that outside of Jurgens we really just didn't land a good quantity of the bigger-bodied, talented offensive linemen until years 3 & 4 (although I think Benhart was class #2 guy).
*Edit: This is why I really want Frost to stay on because I think we could be a pretty good team next season because of how many upperclassmen offensive players we'll have.
