Bill Belichick is a 64-year-old man who started his coaching career all the way back in 1975, when the only technology involved in football was colour television.
Fast forward 41 years and there is more tech involved in the game than ever before, from games being streamed on social media and video replies aplenty, to the tablets that coaches and players use now on the sidelines.
It turns out that Belichick isn't a big fan of those, with the New England Patriots head coach going on an exceptional five-minute rant to say that he won't be using them anymore.

Speaking in his Tuesday conference call with reporters, Belichick has confirmed that after smashing his Microsoft Surface tablet during the game against the Buffalo Bills, he has turned his back on the piece of tech.
"As you probably noticed, I'm done with the tablets," Belichick said in response to a question about issues he had with the tech during the Patriots' latest game against the Bengals in Foxboro, via Engagdet.com.
"I've given them as much time as I can give them. They're just too undependable for me. I'm going to stick with pictures as several of our other coaches do as well because there just isn't enough consistency in the performance of the tablets."
Belichick admitted that some of those problems were unavoidable, but they're not ones he's willing to put up with when dealing with the tablet.
"I'll use the paper pictures from here on, because I have given it my best shot," Belichick said at the end of his answer. "I've tried to work through the process. But it doesn't work for me, and that's because there's no consistency to it."
Both the league and Microsoft have come out with statements saying that they respect the coach's decision to ditch the Surface but added they have received largely positive feedback about the tablets.
The tablets can't have had too much of an effect, as the Patriots currently top the AFC East with a 5-1 record.
