It's pretty hard to find someone these days who doesn't know who Tom Brady is, but there was at least one person last year.
Ichiro Suzuki.
In The Athletic, Peter Gammons relayed a story from 2017 when Brady was seeking stretching advice from the baseball star, but Ichiro had no idea who he was.
Here's what Gammons wrote:
One morning in spring training, 2017, he was in the coaches’ room looking at his cell phone text messages. Ichiro told the coaches about one message he had just received from a number he didn’t recognize. The guy said he’d gotten Ichiro’s number from Alex Rodriguez, and that he wanted to come meet him and study his stretching system.
“What’s the guy’s name?” asked one of the coaches.
Ichiro strolled to the end of the text. “Some guy named Tom Brady. Who the f— is Tom Brady?”
It's not known whether or not the two actually connected, but we're pretty sure Ichiro finally knows who Brady is.
