There are a lot of questions for sure. However most of them revolve around whether they will be allowed too or not. I think it's very obvious the first two on your list could have happened last year if allowed. In order for it to occur they have to ditch the team killing 11 man platoon rotations and commit to someone.
I think Buddy could have for sure. Bogie needs to be a little more selfish and just take the open shot when the opportunity presents itself. The 11 man rotations need to end this year for sure. Joerger seems to be a players coach and I've never heard a player act negatively or speak any ill will toward him but he's going to have to make some players mad this year to get this team where it needs to be and the mad players better be the veterans. ZBo and Shumpert/Temple taking minutes away from the young guys to keep everyone happy is a losing way to coach.
