And Caserio. And an entire department. BB won't talk about it for competitive reasons but the Pats are invested in analytics and have been for years. The Eagles are credited for the analytics movement in the mid-'90s when they had a foot in but Kraft set up an analytics dept right after he bought the team. His was initially for business models for income generation & process improvement but within a few years their attention turned to the football players and, voila!, RBBC became a thing.
RBBC is a model of analytics and how long has BB been doing that?

[The Ravens have heavily invested in analytics in recent years. The Browns, too, but they may need help interpreting what they see. ]
Trading back is another example of simple economic analytics and nobody has done that as much or better than BB, no doubt with Ernie's help.

ESPN ranks the best analytics depts in the NFL - problem is the Pats are so top secret they don't know where to put them.

"One NFL analytics professional called the Patriots a "big black hole" when it comes to revealing any secrets, which of course applies to most everything they do under coach Bill Belichick. But some evidence of the implementation of analytics has escaped the Patriots' gravitational field, and it suggests that the Patriots are one of the most innovative teams in the NFL.
Owner Robert Kraft worked with a former colleague in the 1990s to create statistical models for player valuation. And for the past 15 years, Belichick has relied heavily on his football research director, Ernie Adams, a former Wall Street trader who collaborates with the coach to develop a variety of cutting-edge approaches to team building and game play.
Belichick recently told
The Boston Globe: "Ernie's really a great sounding board for me personally and other members of our staff. Particularly coaching staff. Strategy, rules, decisions. Ernie's very, very smart.''
One major strategy employed by the Patriots has been an arbitrage system in personnel, whether multiplying draft picks via draft day trades or moving their veteran players (such as defensive tackle Richard Seymour in 2009, receiver Randy Moss in 2010 and offensive lineman Logan Mankins in 2014) before they lose value. Based in part on such moves, the Patriots have had unmatched success in the Belichick era, with four Super Bowl rings and counting.
On the field, Belichick's approach appears less consistent. His failed fourth-down gambit against the Colts in 2009 was decried by fans but cheered by analysts who recommend that teams play more aggressively. But in other cases, he has coached rather conservatively, defying his reputation.
Regardless, there is little doubt that the Patriots invest time and energy looking for every edge, and their commitment to ruthlessly outsmarting the competition is a Belichick trademark."
Other examples of analytics are everywhere - Football Outsiders with its DVOA, DYAR, Expected Points Above Replacement - and the list goes on and on. From my pov, if you can measure something, you can make it better, and that's analytics in a nutshell.
Here's a thread I started on Analytics and its application a couple of years ago.
