Yeah, there'll be some sort of reserves games for unsigned guys when the season starts. I've had some concerns about being a PG when there's a lot of them, but teams should be more confident signing more guards than forwards and more forwards than centres because small ball works and big ball usually doesn't (especially with the size you guys all like making yourselves). Each team should be looking to carry at least 2 at the bare minimum, but I'd be signing 3 PGs if I'm a GM. If a PG gets injured you're down to one and then someone pinch hitting there. And unless they're a playmaking SG (like Morgie), they're not going to have the greatest success there if playing significant minutes.
