I'm not sweating the PG, either, except not for the same comforting reasons as mentioned. Iowa hasn't had a commanding, go-to PG since Dev would slide over.
Lot like Iowa football QB's - the PG is a game manager. Not by intent, by the fact that they haven't been able to recruit a high-quality one for years.
That's ok, tho. They've built their recent success on the 4's and 5's, and, even with Kris stepping in and, maybe, improving, he just is not going to replace Keegan. It really comes down to Filip / back-ups showing marked improvement to keep the Hawks in the top half of the conference. They might be marginally better, but, FR is still undersized and I'm not sold that the position will be physically / skilled enough to accomplish the size of step-forward needed.
