How about Mills for Leonard, Meyers from Portland + Blazers 2020 first round pick? Mills is better than Staukas, has played for them in the past and the fans loved him, and will fit well after the departure of Napier. Leonard on the other side hasn't been able to find minutes, but the guy works hard in the off-season, has a nice 3 point shot, and quite surprisignly has numbers very similar to Patty. For example, they have identical defensive rating, they shot the ball from the 3 at the same rate, and have a similar usage and eFG percentages. Leonard could is a better fit for us and will make our roster more balanced.
DJ/White
DDR/Bryn/Manu
Gay/Beli/Lonnie
LA/Davis/Leonard
Pau/Poeltl
I wouldn't go for it right now, but wait and see how Bryn and more importantly White and DJ are playing. If they are hitting their 3 point shots and can play better defense than Patty, I would go for it.
Spurs having 2 first round picks in back to back drafts would allow us to surround LA, DDR, and Gay with some nice young talent. I am pretty sure that all 3 when their contracts are up will sign longer team friendly deals.
