im in the same boat. think i prefer risacher to williams but i wouldnt be upset either way. if the spurs get #1 they still have to do their due diligence on sarr even if its not a positional need. if he's the bpa, you still go with that. his production is pretty mediocre, though, so im not convinced he's the best player.
i also want to reserve judgment on topic until he gets some meaningful euroleague exposure.
a lot of hype on ivisic after his debut, but definitely need more of a sample size there. at the very least his outside shot looks real. i still need to be convinced on the other stuff
depending on where the TOR pick lands, you might not be able to get 2 of the 3 you mentioned, and instead would be taking a shot on a guy like sheppard and betting he can be a full time PG
