Davante Adams was in great spirits after the Raiders eeked out a win over the Jets Sunday night, dancing his face off after their second-straight victory ... and it's clear the All Pro WR is fully behind new coach Antonio Pierce!
The Raiders star WR got jiggy with it after the 16-12 win over Gang Green -- where he had 86 receiving yards -- at Allegiant Stadium on 'SNF' ... his second-best receiving game this season.
Obviously, things are very different in Raiders land since head coach Josh McDaniels was fired .
