Yes, you're right. Robinson played only 6 games that year. Their leading scorer was a 37 year old Nique.
If I'm not mistaken, the next year's 83-84 Rockets, while having a better record due to Ralph Sampson's arrival , had an even more notorious finish to the season, allowing a 38-year old Elvin Hayes, who started 4 games all season, to play something like 50 minutes in his "farewell" home game, an OT loss to the spurs. Edit - here's an article on the 83-84 tank job: http://www.reclinergm.com/coin-flip-to-lottery-did-the-rockets-tank-to-get-olajuwon/
