You can, as I suggested, state a minimum package that you would want for the #3 pick to make it worthwhile.
I'd probably be mad with any trade involving #3 because I would only send him out for a legitimate star, but getting a player like that would probably require more (read: Simons/Shae) which I'm not willing to give up. Like Siakam for #3 + Ant is an overpay. I wouldn't trade OG straight up for #3 so forget about it. A dude like Embiid would take #3 + Ant + Shae which is just too much. Even Giannis, it would take those 3 and multiple future picks which is just too much for me. Maybe Jaylen Brown for #3/Ant is interesting, but not sure they'd do it. Add Sharpe and it's a hard pass. Bridges/Claxton for #3/Ant would be nice but I don't think Brooklyn even thinks about it. I just don't see a realistic trade involving #3 where we don't give up too much. Well... How about #3 + #23 for #1 ? That seems fair
