In Tom Coughlin's day, plays were drawn on chalkboards and maps were things you had to unroll.
Times have changed.
While the former gave way to tablets and the latter to smartphones, the Giants' head coach, whose career spans six decades, has studied the younger generations and adapts where he sees fit with the "millennials."
But one thing Coughlin, 68, can't connect with is Siri, the automated know-it-all on his iPhone.
Telling the story to a group of reporters during the coaches breakfast at the NFL Annual Meeting in Phoenix, Coughlin recalled a recent run-in with the application.
"Two weeks ago I'm trying to get to a roller hockey game that my grandson is playing in, so [Giants vice president of player evaluation] Marc Ross had showed me how to talk to this phone," Coughlin said, according to Newsday.
"I don't trust the lady in GPS, I don't trust her, because they don't send you the right way. I hit the button and I go 'Park Ridge, New Jersey.' And she comes back on, she's giving me directions. So now I figure out where I am. I hit the thing and I said, 'Thank you very much, I know exactly where I am now.' And she comes back and says, 'You don't have to thank me.' I swear to God that's what she said. And then I couldn't get her to shut up. Every turn. 'Take a right here.' I know where I am. I know where I am. I'm a block away from my house and she's telling me where to go. I said, 'I know where I'm going.' "
It's a good thing he didn't ask for the time.
