I think 20 games is about the right amount. Edwards will obviously feast, Haarms will step into more of a scoring roll, Cline will shoot/play a lot more and think he’ll avg around 12. Eastern will at the very least be an elite defender. Then you have a crop of Sasha/wheeler/hunter/Williams that you’ll need a couple to contribute to the offense but I’m confident they will. Purdue should be a really good defensive team next season though.
I think 18-20 is a reasonable range; a lot will depend on the conference's depth, as this will be a transitional year in the league. I think 12 ppg might be asking a lot out of Cline - just keep in mind for as well as Dakota has played this year, he's only averaging 12.1 ppg.
I think Haarms has plenty of room for growth, but his value offensively will be determined by how dangerous he can be in PnR and PnP action. I do worry about spacing for next year, so hopefully Wheeler has developed a consistent jumper; otherwise we will likely need to see some lineups with Cline and Stefanovic, which could be a little iffy on the defensive end.
Will be a nice challenge for Painter. Can't allow for a backslide after everything this senior class has done to get things back on track.
