I think the only reason Mahaney is starting is simply Hurley trying to keep his confidence at some acceptable level. He knows Hass can handle either role.
But the bigger picture is he just won two chips with starting back courts that were all 6’5” or taller except for Cam who was 6’4” but rebounded like he was 6’7”. Sure we had Joey C coming in for instant offense and Diarra both years but they were off the bench.
Look at our incoming recruits all big guards except for the big guy Riebe, who auto corrects to Reuben which should be fun, Hurley likes big guards and he is not shy about saying it.
Personally, my starting lineup would be Johnson, Karaban, McNeeley, Ross and Ball. I could see Diarra starting over Ball but that is the only question mark for me. Then Diarra sixth man again, Reed Jr and Stewart there is our perfect 8 man rotation. Mahaney needs to figure out how he can play a role like Joey C. Until he defends better that has to be his role. But Joey had swag, Mahaney not sure has that showman in him not with his current body language.
I hope I am wrong about Mahaney, never want to see our guys struggling.
