Those best equipped to describe Bill Belichick's football genius are the players he shares that genius with.
Take it from Patriots cornerback Stephon Gilmore, who's developed into one of the best defensive backs in the league since coming to New England in 2016.
In a recent interview with Sports Illustrated's Conor Orr, Gilmore recalled a detail Belichick shared with him prior to a 2018 game that may go overlooked on other coaching staffs.
"He said, ‘When the ball is traveling in this certain direction, the wind is blowing hard enough where you should probably trail the receiver just a little bit because the ball isn’t going that deep,' " Gilmore told Orr.
"I mean, nobody looks at those kinds of things. It’s the little things like that. You listen to him."
Gilmore seemingly reaped the benefits of Belichick's extra insight, too. As Orr points out, both of Gilmore's interceptions in 2018 came in outdoor stadiums -- Week 1 vs. Houston Texans, Week 11 at New York Jets -- on underthrown deep balls. (You can see them at the 0:01 and 6:17 marks of the video below).

Gilmore's anecdote shouldn't surprise you: Belichick is famous for leaving no stone unturned and makes a habit of surveying the field several hours before a game to gauge everything from wind speed to field conditions to the position of the sun.
But every once in a while, a player like Gilmore gives us a reminder that Belichick's relentless preparation hasn't changed as he enters his 20th season as Patriots head coach.
