While San Francisco 49ers wide receiver Kyle Williams is being blasted by fans on Twitter for Sunday's Super Bowl miss, there is one die-hard fan out there who thinks the young NFL player should be proud of his achievements: 7-year-old Owen Shure, from Los Angeles.

Shure wrote a heartbreaking, yet inspiring letter to Williams, telling the 23-year-old player that he is his No. 1 fan and told the player thank you.

Williams' inexperience was seen during the fourth quarter of a disastrous NFC championship game on Sunday, when he made a few fumbles and cost the 49ers a shot at the Super Bowl. Williams was the target of much hateful comments and death threats on Twitter, things the player said he didn't pay much attention to.

you should jump off the golden gate bridge for that one, I hope you, youre wife, kids and family die, you deserve it and Jim Harbaugh, please give @KyleWilliams_10 the game ball. And make sure it explodes when he gets in his car, were just a few of the death threats sent in Williams' direction.

Williams has said he accepts responsibility for the bad plays. But to Shure, Williams and the 49ers had a great season.

Ben Mankiewicz from the Huffington Post passed along a letter written to Williams by Shure, his friend's little boy, and let's say the kid is a true fan. Here's the full text of Shure's handwritten letter to Williams (the grammar isn't corrected).

Dear Mr. Williams:

We just watched the Playoff game. I feel really bad for you but I wanted to tell you that you had a great season. you sould be very proud, so I wanted to say thank you.

I am your #1 FAN!

p.s. your awsome

Mankiewicz wrote that when the 49ers lost Shure was sad, crying and asked, But... why... did he... have to... fumble?

And in an effort to get the boy to stop crying his father asked him, If you feel this way, how sad do you think Kyle Williams is? It was at that moment Shure asked his father, Can I write him a letter to make him feel better? Mankiewicz wrote.

The 7-year-old put pen to paper, scribbling the kind words to Williams.
