As others have said, the staff absolutely needs to hone in on a grad transfer point guard, that's priority #1. I don't hate what Bolton has done at PG since Haliburton went down, but he's much more suited off the ball. Walker will probably see some minutes early in the year, which will probably determine his viability come conference play. Jackson has improved, but needs to get bigger. If Caleb Grill can get the lid off the basket he will be a quality option off the bench.
Young, Foster and Conditt is a pretty good core in the interior.
The biggest question is what the wing positions look like. At this point I'm not sure we can rely on Prohm giving Terrence Lewis minutes, and I don't know what to expect with Zion Griffin or Javan Johnson. Maybe Blackwell is ready to contribute right away?
As others have alluded, this is the biggest offseason for Prohm at Iowa State. He needs to land a guy or two, and guys we have absolutely need to improve.
