So Kenpom actually tracks the percentage of time each specific lineup gets. Over the last five games the starting five of DJ, Edwards, Thiero, Reeves, and Ugo have been getting 12.6% of the minutes. The only lineup getting more time than that is Reed, Dillingham, Reeves, Thiero, and Ugo at 13.7.
So it's not really like the starting five is getting quick minutes to start and then another lineup of five guys are getting a ton more minutes. We just have so many lineup combinations that one single group of five doesn't really get the bulk of the minutes, regardless of what five that is.
And this is the depth chart over the past five games. For everyone complaining about DJ, you should note that Reed gets the vast majority of the PG minutes.
