I agree, No 3 month rentals.
But, if you have the chance to acquire a young center, or a young wing player for Lee, or free agent to be Sully, and a lower draft pick or two, DA should do it. Allow the young player to play and grow, while you hope for a free agent signing, or the drafting of a top college player using the Nets pick.
There is such a thing as accumulating too many draft picks, soon you won't be able to see the forest through the tree's.
