My very ignorant view on what I'd like this off-season:
Mose has got to go. Doesn't matter who we put on the floor if we're running the "offense" we've been running. We need a coach who won't wait until it's a 20-0 run before calling a timeout, or keeping challenges like they carry over between games.
Weltman can stay (for now), but only if he can sign a head coach that will get this offense where it should be with what we already have on the roster. And he needs to get a true PG, and a defensive big. If he can't (or won't) get a true PG or a defensive big, or fire Mose, then he can turn in his badge too.
Suggs needs a "come to Jesus" meeting. Weltman is bringing in a true starting PG so Suggs can slide to his natural 2-guard spot. But he needs to fully embrace the "3 and D" role, and any hero-ball type play results in a trip to Osceola.
The medical team needs to go. It's been 2-3 seasons in a row where the top players on this team are basically missing the season because of injury. Find a way to get House MD or something.
Franz and everyone else needs to skip playing international ball this off-season. Give your body a rest for a change, might help them actually heal up a little.
Every player on this team needs to be locked in the gym every single day, with no food or water, until they can make 10 3s in a row and 50 FTs in a row. Someone dies of dehydration, then a roster spot opens up.
