I guess I see it more as:
1. Jackson
2. Wigginton
3. Babb/Egor/Brown/Edwards
4. Juiston/Young
5. Young/Lard
Agree with this for a starting 5. But what's interesting about next year is that so many will be in the running (at least from the outside looking in) for the available minutes.
What if Lard is a much better rebounder than Solomon? What if Lewis' 3-point shooting "forces" coaches to play him major minutes? What if Jakolby is really good (but we couldn't see it as he was behind multiple seniors this year)?
It should be fun to watch. (This won't be a popular analogy but it'll be how Hawkeye fans surely felt about their team this year, albeit we'll have a better record at the end of the year.)
