How to unlock the G Recovery achievement in NBA 2K11 - Definitive Guide
At the beginning of the game before the tip-off, hit and scroll down to options > coaching. Turn substitutions to manual and timeouts to manual. Then exit out by hitting , and play the entire game with 5 minute quarters. At the end of the game the trophy will be yours.
This must be done in a game with at least 5 minute quarters. Sliders can be adjusted and difficulty altered. Can be done with two controllers and rules adjusted (shot clock off). This will not unlock in My Player mode.
On the main menu, go to Settings > Coach Settings then find substitutions and turn it from auto to manual. Just play the entire game and this achievement will unlock. You don't even have to substitute anyone if you don't want to.
