Do you remember New England Patriots running back Jonas Gray? On November 17, 2014, Gray rushed for 201 yards and four touchdowns to lead the Pats to a 42-20 win over the Indianapolis Colts.
Gray had only rushed for 133 yards in three career games prior to that breakout performance, and he only rushed for 256 more in the next year-plus of play. He's been out of the league since the end of the 2015 season.
The point here is that sometimes, it's not the big names that put up dominant, otherworldly performances. Sometimes, it's players you may have never heard of before seeing them on television, like Chicago Bears rookie running back Tarik Cohen, who has been fantastic in his first three games.
