The one thing Fran almost never does is manage his lineups to make sure they are good defensively. The weakest defenders are Krikke, PMAC, and Sandfort. Sandfort rebounds pretty well, PMAC is the worst rebounder. PMAC also the worst of the three on offense/shooting efficiency.
I think your lineup is sound, but having two minus defenders out there at same time (Sandfort and Krikke) makes it hard to defend, Obviously Sandfort and Krikke are plus scorers most of the time.
I don't think any sane B-ball coach would start 4-forwards (Krikke,PMAC, Sandfort, Freeman) and a shooting guard...but Fran has that as his starting lineup because 1) He wants maximum offense 2) He doesn't care about defense 3) PMAC has to start because Fran runs the Iowa team to maximize his boys playing time.
The only way PMAC gets taken out of starting lineup is if PMAC himself asks to come off the bench.
