Three-time Super Bowl champion Ed McCaffrey was an incredible NFL player but he was never as good as his son, Christian, leaving many to wonder where the heck such athletic genes came from. 

If you ask Christian's mom, Lisa McCaffrey, he got his insane athletics from his "real" dad: Shannon Sharpe. 

Sharpe and Ed played together at the Denver Broncos, so it's not too far-fetched that Lisa snuck away for an affair [KIDDING]. 

Lisa went on her "Your Mom" podcast, alongside co-host Ashley Adamson, where she revealed that she and Sharpe used to joke about him being Christian's "real" dad back in the day. 

"He used to go in these games at halftime when he was playing Pop Warner," Sharpe reminisced, "and he was the little running back and they'd pitch him the ball and he probably had a hundred touchdowns that year he was unbelievable."

While Sharpe saw potential in little McCaffrey, he admitted that he never thought the kid with whom he would play Power Rangers with in the locker room would turn out to be this good. Nobody did.

"It's unbelievable seeing what he's doing now," Sharpe said. "I mean yeah he's around it, his dad played. His dad was an unbelievable teammate, he was a great player. But you don't think that somebody just sitting on your lap twenty-plus years later is going to be playing in the NFL and be one of the premiere players in all of football."

So, where did Christian really get all of this talent from if Ed is the father? 

"You know what I tell people, Lisa," Sharpe said. "I say I played with his dad but I believe his mom was the better athlete."

Lisa was a former soccer star at Stanford where she met Ed.  

"You're probably right," Lisa said. 

Lisa was very open about how shocked she was watching Christian take such huge strides at every level of football he played and shared that it did not hit her until the 2018 NFL Draft when he went eighth overall that he really was pro-ready. 

"Honest to God, went he got drafted," Lisa said when asked when she knew that Christian was good enough to play in the NFL. "I knew he was going to be drafted but at every level we were insecure. Can he handle that level? And then he excelled. Even after the Heisman year … you're never satisfied and he wasn't either." 

Now, she and Sharpe get to watch "their" son compete for a Super Bowl ring against the Kansas City Chiefs on Sunday. 

"Thank you for giving Christian everything that he has," Adamson chimed to Sharpe at the end.
