I don't see how this is a big deal really, it is college BB. You usually have a position that you need to address. Heck you might lose someone to the NBA draft or transfer in the spring and you gotta find something on the transfer market right then and there.
I agree with your comments (from another thread) that Iowa's roster is still imbalanced and they need 1 more guard. If they decided the guys they have their eyes on are just borderline guys who are not going to get playing time next year, I understand the pass. But if they evaluate as a guy who can handle the ball for 5-10 minutes off the bench or provide some modicum of perimeter threat, don't you think it will be worth it to take the plunge for the '19 class?
