I can think of 3 ways we might pick up a late first this year:
1. When we hear Irving and Williams get selected 1 and 2, then we get on the phone with Washington and trade our #3 for their #6 and #18. I think if we were to do this, we'd probably select a PG with #6 (Knight or Walker) since they'll be the BPsA, thus this doesn't really speak to the OP
2. Trading CJ Miles (as you mentioned). I know their might not be a long history of this type of deal, but this is a strange year. I've already mentioned in another post trading CJ for #20. I can see that happening.
3. Dealing Tomic's rights. For a late, late first or an early second. Mack should be in range there, and maybe one of these dudes you mentioned will fall. I don't know enough about the late-first round to comment.
While we'd likely be worse next year for trading him, I think we SHOULD trade Harris. Portland wanted him last year, and they have a glut of SGs, something we need (ahem, Matthews). Maybe their poison pen can be put to good use.
Can we even do #2 during the draft? We'd have to pick up his option this year first to do so but can't til a new CBA/July 1st+, no?
