Kyle Shanahan has high praise for Christian McCaffrey.

The San Francisco 49ers head coach attributes his success to the “obsessive” mentality of his star running back, even though McCaffrey was unable to play in the preseason due to a calf injury.

So much so that Shanahan, 44, suggested the NFL star was probably thinking about football during his recent wedding to Olivia Culpo.

“As he walks down the aisle, he’s probably thinking about his feet and how to take the right path,” Shanahan told reporters. “No offense, Olivia.”

The veteran coach added: “He’s obsessed with it. And when you get into situations where you get injured and can’t do all these things, at least he’s put in the work beforehand.”

As last season’s NFL rushing champion, McCaffrey helped lead the 49ers to the Super Bowl.

Despite his team’s heartbreaking loss to the Kansas City Chiefs in the final moments of the game last February, McCaffrey made good use of his offseason and married his longtime love in June.

The 32-year-old model and the 28-year-old NFL star were married on Saturday, June 29, in their home state of Rhode Island.

And when it was time to walk down the aisle, it was important for CMC to do so in a church, Culpo said fashion“That was our top priority,” she said of his preference for the location.

The former Miss Universe wore a custom-made dress by Dolce & Gabbana while the athlete reflected on his fiancée’s path to the altar.

And while McCaffrey’s status is still uncertain – his goal is to return to the field in time for the first game of the season – his coach is certain of one thing.

“He knows what it takes to play in this game, especially at his level,” Shanahan said. “And not many people play at that level unless they’re like that.”
