Thanks to his heroics on the field and his starring role in his team's critically acclaimed "All or Nothing" Amazon Documentary, NFL fans have become well acquainted with second-year Arizona Cardinals running back David Johnson.
The 2015 third-round NFL Draft pick has already experienced enormous success on the field, recording over 130 total yards in each of the Cards' first two games this season. He's had big things happen in his personal life, too, thanks to his recent wedding and news that his wife Meghan is expecting a baby boy.
But there remain a number of interesting things about D.J. that you won't learn by watching him embarrass opposing defenses or by viewing all eight episodes in "All or Nothing." Here are a few additional items you might not know about the Cards' star rusher, which we learned during Monday's Cardinals Countdown Facebook Live event at Big Red Brew Haus inside University of Phoenix Stadium.
1. He's a triplet.
Johnson is one of six children, and he also happens to be a triplet with sisters Danielle and Darnecia.
"Growing up, they were always bullying me -- trying to bully me. I was a little bigger so I was able to hold my ground," Johnson said.
Since twins and triplets sometimes run in the family, Johnson realizes one or the other could be in his future. "That would be crazy to have triplets or twins, but it would also be a blessing," he said.
2. He starred in two other sports.
Before focusing on football, Johnson was also a basketball and track star at Clinton High School in Iowa.
One of the NFL's fastest players, Johnson put his speed to good use when he finished in second place at the 4 x 200 and 4 x 400 relay at the Drake Relays in Des Moines, Iowa. He was also a second-team all-conference basketball player as a high-school junior.
3. He wouldn't mind trying "Dancing With the Stars."
During a fan Q&A before Monday's Cardinals Countdown, Johnson was asked whether he would be interested in appearing on a future season of "Dancing With the Stars."
He didn't say no.

4. His baby is due a week before the Super Bowl.
Johnson hopes he and the Cardinals will be in Houston on Feb. 5 for Super Bowl LI -- but if that happens, there's a good chance Johnson will have a lot on his mind, as Meghan is due to give birth Jan. 29, exactly one week before that game.
"We're cutting it close," Johnson said. "Hopefully, God-willing, we make it to the Super Bowl. Everyone's calling it a Super Bowl baby."
5. He's a devout Christian.
Despite the immediate success and stardom he's received since arriving in the NFL, Johnson has been able to maintain his humility thanks in part to his faith in something bigger than himself.
"I'm a Christian, so God has always taught me to be humble," he said.
