Spurs likely taking Harper at #2 will result in them playing a lot of 3 guards lineup. It makes a player, who is primary a SF, like McNeeley, less attractive than before the lottery.
Fleming's profile is even more perfect now for Spurs. Spurs fifth player alongside Fox, Harper, Castle and Wembanyama can play a Bowen like role on the offensive end. The main question about Fleming is whether or not he is a good player behind his great profile.
Spurs could gamble on some young high upside prospect like Asa Newell, Carter Bryant, Essengue or even Beringer.
