Rajon Rondo the Blazers PGOTF?

Rajon Rondo in years passed has been rumored trade bait, sources say he could possibly be available again for the right price, with the Celtics championship window closing and the Big three only getting older and more feeble could Rajon Rondo be had?  Could this happen? what would you give up for him? Rudy, Nicolas, Andre and a draft pick?  Salaries aside I believe this move automatically makes you a contender again
