I'm a fan of Shep (Stats nerd), but I wouldn't take him at 1. Not sure he's a genuine #1 level on ball creator, and if you're getting a Red type with better defensive event creation, that's a valuable player, but it's a solid role player, not a star. The reason Curry is so good is that he can be a major threat on and off ball with shooting and speed of release. If the Spurs think Shep gets there, fine, but I don't think he's showed that level of on ball juice.
Second round should get some interesting cheap depth flyers coming through. Kel'el Ware and DaRon Holmes are pretty consistently mocked near the end of the first, I think they're interesting bets with the early second round pick if they fall.
The other interesting guy to pre-draft is Connor Murray-Boyles. He's been outlier good recently, can't shoot but the FT% is OK, and he's super young. Doubt he comes out this year as the archetype isn't highly valued, and he probably jumps a lot if he does the recent stuff for a full season, but I think he's an NBA guy.
