I've landed on 4 being the right number for me.
When you do these rankings, what matters most of anything is elite traits (offense / defense). Illinois is most likely the best offense in the country, as Torvik projects. That immediately gives them a high ranking.
Florida and Duke should be top 5 in both, so having Illinois above them I wouldn't agree with at all. (Our defense is likely going to be in the 20s, maybe late teens, especially since we lost our two best defenders in Ben and Kylan)
After those two I don't see any "top 5 in both" teams, but UCONN is right on that cusp, and could be TOP 10 in both. Plus, considering they've beaten us over and over, they should be ahead.
Michigan lost 3 lottery picks. There's too much "projecting" with that roster. And, they lost their coach, so I wouldn't have them ahead of us.
Of course none of this is set in stone on July 1st, as always the case with preseason roster outlooks.
