If he chooses the Hawks, Nelson and Krikke seem like the most likely to start at 4/5. Brauns seems like a solid back up, mostly at 5. It is really hard to judge whether the freshmen 4/5s will be ready to step into more than spot minutes, but they both look like really good players. Not many players redshirt nowadays, but the one least ready to play might be a candidate. I'm not sure what to make of Mulvey. He could still be a solid contributor, or he could be looking to transfer after sitting on the bench again this year. Riley seems like a great kid, so I hope he can step it up.
Nelson would give us some really good depth in the middle, to go with a logjam at 3 with Patrick and the Sandfort bros, who all should be ready to contribute. Tony and Dix should be really good at 2. Bowen and Harding are very talented, but I cant really predict how well they will play against top D1 competition. I expected a lot more from Bowen last year, and I expect he will be a lot stronger and ready for physical play. Harding looks great in the tapes I have seen. He has everything you want in a PG, except maybe size. If those guys play up to how good I think they can be, Iowa could be a huge surprise.
