While it had surely happened before Jack Hoffman (a seven year old boy battling brain cancer) raced 69 yards for a touchdown during Nebraska's spring game, it was the viral video of Hoffman that captivated the attention of the nation this past spring.
Since then, a number of teams have given kids feel good moments of their own, the latest of which being the Cleveland Browns who had a five year old cancer survivor name Ryan Encinas race 50 yards for a touchdown to wrap up one of their recent practices. If you keep a close eye on little Ryan after the handoff it looks like he start to celebrate a little prematurely just before passing the line of scrimmage.
This kind of stuff is awesome, especially when you see an NFL program doing their part to help. When you really take the time to think about what this will forever mean to a young kid and his family, moments like this will never get old and this is the stuff that helps to keep us all grounded.
