Matthew Stafford's Wife On Podcast Comments, 'Probably Worst Thing I've Done'

Matthew Stafford's wife is admitting she made a mistake by going public with the quarterback's communication struggles in the locker room ... calling it, "probably the worst thing I've done when it comes to him."

Kelly made headlines after revealing the 35-year-old Rams star wasn't connecting with his younger teammates on her "Morning After" podcast last week ... when she said the Super Bowl champ has found difficulty vibing with guys compared to years past.

Now, Kelly is regretting her decision to share that info ... telling Local 4 in Detroit, "That was tough. I say all the time, probably not the best if your wife’s name is in the media, if it’s talking about sports."

"I felt pretty bad last week," she added. "I put my foot in my mouth pretty good last week."

The mother of four explained she thought the topic was relatable ... and she still believes it to be a true statement.

"But I'm not in an NFL locker room, I'm not spending every day with these teammates."

Rams coach Sean McVay commented on Kelly's statements earlier this week ... saying he took it like more of a joke at Matthew's age instead of a real issue within the team.
