Jason Kidd underwent significant knee surgery in the offseason and NBA GM's do not overlook that fact.  Kidd is in his 30s now and may not be that same player that led the Nets to the Finals two consecutive seasons.

And for this reason no trade involving Kidd is imminent, as GM's will want to see how he has recovered from the surgery in actual play before giving up a few quality players and/or draft picks for Kidd and his massive contract.
