Not sure where else to ask this, so I'll try here.
I read that due to the upcoming expansion draft a team trading a player after 1/1/17 couldn't reacquire that player until after 1/1/18. But now I can't find any references to the rule. Such a clause makes sense because it would prevent a team from trading players they couldn't protect to a team with "spare" slots and then reacquiring them after the expansion draft.
I did find the clause regarding Vegas not trading players they draft back to their original team until after 1/1/18.
Can anyone provide a link that verifies the broader rule? Also, if the rule is in place, does it also apply to pending UFAs that were traded as "rentals"?
