I don't know if I could even come up with 10 things I've learned, since I feel that things have played out exactly like most of us realistic fans have expected.
1- trayce is still really good without any evidence of an outside game or a right hand
2- depth will be an issue
3- Jalen and Malik are the real deal talent wise
I think the one thing I can say I've learned is that I absolutely trust Kopp as a starter (and getting starter minutes) more than anybody else in that spot. In the offseason I was tempted to consider Bates/Geronimo, but Kopp has the poise and consistency.
