Samanic, Devin, Primo, Sochan were not the BPA's. Wemby and Castle were obvious. But Spurs have always been searching for that "Spurs typical" player, a mobile big like Diaw (Samanic, Sochan), a defensive guard (Devin*, Primo). And heavily relied on their performance at the Combine. Lonnie tested high on vertical and lane agility. Honestly Spurs' scouting has been underwhelming missing out on Haliburton, J-Dubs, Sengun, Tari among others.
Rebounding and a big bruiser to help Wemby are the obvious needs, plus a backup PG. I'm hoping a combination of Queen/Sorber and Fleming/Bryant/Wolf, and a backup PG someone like Boogie Fland in the 2nd round.
