Griffin suffered a rather tortured time in the team when under the guidance of former coach Mike Shanahan, but the player has now admitted that there are no ulterior motives at play under their new boss.
"What I think is going to help us most this year is that everybody in that building is going to be for us being successful and for us winning," Griffin told reporters.
"There are no ulterior motives. That will be great. Jay has been phenomenal. [General manager] Bruce Allen has done great job of getting the right guys in that locker room.
"I tip my hat to them. They have given us everything we need to be successful. We're going to work our butts off for them."
Griffin made his name playing college football for Baylor University, before being selected by the Skins at the NFL Draft in 2012.
