Being named a finalist for the Heisman Trophy has at least one thing in common with running for President: The public will dig up your past and post it on Twitter.

In Christian McCaffrey's case, the past apparently involves many broken tackles and touchdown runs in NFL stadiums. So not much has changed in over a decade, right?

Wrong.

A seven-year old McCaffrey used to celebrate his touchdowns by pulling a Sharpie out of his sock and signing the football -- just like Terrell Owens did in a 2002 game. The Denver Broncos dug up video evidence on Tuesday:

One can see an early prototype of McCaffrey's current running style in his 35-yard scoring scamper. This was a game of kids-against-mascots, and the future Stanford star, whose father, Ed, was a receiver on the Broncos, made one miss before a teammate pancaked another.

"The kids seriously thought they were playing in a Super Bowl," Lisa McCaffrey, Christian's mother, remembered. "The mascots actually were a little salty because the kids were going all out."

The effort extended to the scoring celebration, and Lisa isn't sure what drove her son -- whose reactions to touchdowns these days are much more understated -- to emulate Owens' antics. But she has some ideas.

"He was playing with his older brother (Max McCaffrey, now a senior at Duke) and all his friends," she said. "I think they made him do it ... I remember Max and his buddies being super psyched that he did it after."

We're excited that a young McCaffrey graced us with some memorable theatrics, too. And Lisa still doesn't know where Christian found the Sharpie that he stuffed into his sock before playing, so that's a fun twist.

In retrospect, though, perhaps McCaffrey should have celebrated a little differently as a seven year-old. Heisman pose, anyone?
