Switch Ivey and Utomi and I think you are on point. IMO, Ivey is a 1 or a 3 due to his slashing ability. Utomi, now that there is no way he plays as an out of position 4, is a natural 2. His high-arcing jump shot is basketball orgasim when that goes in (which it does at a high clip).
Sales isn't a 5, but between him/Jackson/Williams, somebody will likely have to play some minutes there (barring a JUCO). But, IMO, may not be a horrible thing since this team (especially under Groce) will thrive next year if it can get up and down the court.
