We really do need a guard (PG/SG) that can handle the ball and create his own 3 pt shot (yes 3 pt shot) when being guarded 1 on 1.
Jordan had it early in his career until he didn't, and I suppose you could blame the hip injuries/surgeries. Mike Gesell was just too small to be the kind of scorer we need in that situation and be a team that can hang with elite teams/athletic teams. In fact, I'm kind of over the 6'0 ft and under PGs for a while. Even Joe, as fast as he is, has limitations because of his size.
One of the things that made Dev Marble probably our best 1 on 1 3pt shooting guard in recent years was he had the length to create his shot and not let the defensive presence bother him as much.
But I suppose we can say it's hard for Iowa to land those kind of guys, so we're stuck with shorter guys like Bohannon and Toussaint, who in their own way can do certain things really well, but also have glaring flaws that will eventually get exposed by better teams.
