I remember the Spurs beating Denver last time they played them. I think Jokic had a monster game 37, 11, 11 and Murray had something like 20+ as well, but we still won. I wasn't able to watch the game, but was pleasantly surprised seeing that we won against them. Not sure how hard Denver played that game, but I remember being very encourage with the win thinking the Spurs are pretty good when close to full strength.
I agree about DWhite (I'd really like DWhite back, though, but I think you're right, he doesn't fit the timeline) and AReaves. I think Reaves may have overperformed.
I'd love to get Caleb Martin, though. I don't know if I am remembering right, but I thought during game 7, Reggie Miller kept saying "cha-ching" every time he made a bucket then saying that he's going to get a bag of money, so I assumed he was a free agent, or am I remembering wrong? Was Reggie talking about someone else such as Gabe Vincent?
As for the roster construction, this is a very hard thing to determine this early. It really might be worth it giving it a season to see how it goes, but also getting the right players earlier on could make a big difference to the development of Victor and the team. I am really not sure what direction to go in yet.
