Question about trading rookies

[diconzo]

My question is does anyone know if we can keep our 2 first round players unsigned until free agency and our cap space kicks in and trade their rights to someone (Utah) for a capable big (Paul Millsap) or another player once we have our cap space? (Paul Millsap) Or are there rules against keeping them unsigned for a month or so? I know first round draft picks have to be signed but can you trade their rights after draft night?

I believe there is a cap hold on unsigned rookies. Combined I think they'll hold at around 2 million.

Note that even though a draft pick's trade value (for salary matching purposes) is $0, a first round pick is included in team salary at 100% of his scale amount once he is selected in the draft, unless he signs with a non-NBA team (see question number 48) or agrees in writing not to sign an NBA contract that season (see question number 14). If an unsigned first round draft pick is traded, then 100% of his scale amount is included in the acquiring team's team salary as soon as the trade is completed. An unsigned second round pick does not count toward team salary.
