The 49ers have delighted their fans so far this season with a perfect start to the campaign, but there was likely none happier than the young supporter who had the chance to meet several of his heroes ahead of Sunday's win over the Cardinals.

A 49ers fan on TikTok posted a video of his son encountering a host of their star players, including the NFL's rushing and scrimmage yards leader Christian McCaffrey, en route to the Week 4 game and requesting autographs.

@izzygordo Thanks for the @San Francisco 49ers for stopping and showing love, that made my sons’ year!!!! #49ers #fttb #bangbangninergang #ninerfaithful #nfl #fyp ♬ original sound – Izzygordo

McCaffrey, George Kittle, Javon Hargrave and Fred Warner were more than happy to oblige, signing the young fan's regular helmet.

The youngster's delight was clear for all to see, and the 49ers made a day to remember even more special by subsequently cruising to a 35-16 win over the Cardinals to improve to 4-0.

It would easy for the Niners to dismiss such autograph requests, especially on a gameday when they are fully focused on the task ahead.

But their stars understand that how they conduct themselves off the field and interact with their fans is just as important as what they do on the field. The willingness of McCaffrey and Co. to provide a young fan with memories that will last a lifetime makes them an easy group to root for.

It would make his MVP case tough to dispute.
