Mario Williams Twitter jabs Tom Brady

It's not taking long for new Buffalo Bills defensive end Mario Williams to establish new rivalries in the AFC East.

New York Jets left tackle D'Brickashaw Ferguson sent a jab Williams' way soon after he signed a $100 million contract with the Bills. Now, Williams is jabbing back at a different AFC East target: New England Patriots quarterback Tom Brady.

Williams recently changed his Twitter avatar. In it, Williams is playing Mario from "Super Mario Bros." and he is throwing a fireball at a helpless looking Goomba Brady. Williams will be going after Brady a lot over the next several seasons.

While it is only a Twitter jab and nothing to get too excited about, I do think it says something about Williams' mindset. He recognizes Brady and New England are at the top of the mountain in the AFC East, and Williams was given the huge contract to help Buffalo close ground and eventually supplant the Patriots.

Williams and the Bills are hoping life imitates art this upcoming season.
