The impressive rookie season Marcus Williams put together ended in pain when he missed a tackle on Vikings receiver Stefon Diggs in the playoffs, allowing Diggs to race 61 yards for a touchdown and the "Minneapolis Miracle."

Williams vowed after the game to do everything he could to make sure a play like the one that ended the Saints' season never happens again.

On Wednesday, Williams released a video on his Twitter and Instagram accounts showing how he's working on doing it this offseason. The video opens with the Diggs play, then shows Williams getting up at 5:23 a.m. and working out. 

Over the video, the sound of Al Pacino's locker room speech from the movie Any Given Sunday plays, a speech that focuses on how football's a game of inches. 

Williams has a lot to build on from his rookie year. The second-round pick was a key part of one of the most successful rookie classes in Saints history, racking up 73 tackles and four interceptions, the most for a New Orleans safety since 2009.
