When does Danny have until to sign Mickey and Holmes?
All year?
Teams should really be able to designate second-rounders to the NBDL without signing them while retaining their rights.
Agreed. But some clarification. I think teams should be able to SIGN rookies to a contract, designate them to the NBDL & have them NOT COUNT as roster space.
Right now there's nothing preventing Mickey from signing a contract with the NBDL team on his own (that I know of), while the Celtics retain his rights. In fact, as I understand it, as long as Mickey is playing professional (and I think the NBDL counts) the Celtics would retain his rights for one season at the conclusion of said non-Celtics contract.
As for Holmes, well he went undrafted, so it doesn't apply... but that's where my clarification comes into play, being able to sign them, send them to NBDL, and have them not count towards roster space. AKA, a genuine farm system.
