Not sure if any of you watched the NBC broadcast. In it one of the commentators mentioned that Hamilton had intentionally bunched up the group to allow a 10 second gap for Rosberg during the SC period. The commentator said that this was part of the team strategy, so Ham ending up in 4th means he sacrificed his own race for Rosberg.
This is BS. Ham was closing on to Rosberg before the SC, and they were faster than RB on both tire, and had less degradation.
