If you thought Knowshon Moreno's career-best performance last week in New England was impressive, wait until you see the tears he cried before Sunday's game against the Kansas City Chiefs.

After struggling with fumbles earlier in his career, Moreno is having a splendid season for the Broncos this year. His nine touchdowns are second to Adrian Peterson, and his performance against the Patriots (37 carries for 224 yards) was the best of his career.

Perhaps realizing that he is in the midst of the best season of his career, or because he just loves the national anthem, Moreno was caught bawling before the Broncos matchup with the Chiefs. And his tears weren't normal tears. No, they were pretty special.

Naturally, Moreno's showing of emotion set Twitter abuzz.

Moreno finished the game with 18 rushing yards on 15 carries to go along with 72 receiving yards and one touchdown in Denver's 35-28 win.
