So when you give them the environment, they’ll usually respond in a positive way.”But while the great coaches demand discipline, they also figure out ways to get their teams to bond. “But it is important to clear the air so there is no speculation on it from week to week.”Tom Thibodeau, coach of the NBA’s Minnesota Timberwolves, spent time with Belichick a few summers ago and said he marvels because “the infrastructure is so strong” – one factor that allows great coaches to say goodbye to key players without missing a beat.“You either conform and become a team-first guy, or you won’t be there long,” Thibodeau said. Eventually, he recognized the Cowboys could only succeed with one of them, and he chose Staubach, while trading Morton to the Giants.“Sometimes it is unfortunate to have to make such a decision,” Landry said at the time. The same might have been said, or asked, about Noll, Landry, Saban or any of these coaches, whose time facing the public usually involves five- and 10-minute segments with the media during which their main goal is to not reveal anything important about their game plan – or much about themselves.The effort – and sometimes, accolades – they get from their players says more.Terry Bradshaw couldn’t stand Noll on their way to winning four Super Bowls. That person who’s going to be good, who has potential, that’s going to get you fired.”A lot has been made this year of New England’s decision to part ways with two key cogs in its defence – Chandler Jones in the off-season, then linebacker Jamie Collins, who was (ruthlessly?) traded away to winless Cleveland in October.The Patriots’ defence still allowed the fewest points in the league.Belichick is hardly the first coach faced with those sorts of choices. In the 1970s, Landry spent a season shuffling between Roger Staubach and Craig Morton at quarterback. It’s also a description of Chuck Noll, Tom Landry, Nick Saban, Greg Popovich, John Wooden and pretty much every other person who has cemented him or herself on the Mount Rushmore of coaching.“Xs and Os are the price of admission,” says John O’Sullivan, founder of the Changing the Game project, who speaks often about the importance of coaching in society. “That time in Cleveland probably helped me as much as anything in developing the kind of philosophy and organizations that have helped us be successful through the years. Only when he let up a bit, then got Michael Strahan on board, did the Giants become winners.This year’s other Super Bowl coach, Dan Quinn of the Falcons, has discussed his season-long quest to turn his group of players into a “brotherhood.”Belichick will never be confused as warm-and-fuzzy, though maybe Vince Wilfork’s tweet after parting with the Patriots in 2014 painted the best picture of the atmosphere the coach has created: “We are always family,” Wilfork wrote.And while great coaches have some hard-and-fast rules about how they want to run their teams, the best of them are always keeping an open mind toward learning.Famous are the stories of Belichick’s willingness to go the extra mile – especially in the film room – from the time he got his first NFL job, as an assistant to Colts coach Ted Marchibroda in 1975.“The impression he made on colleagues was almost universally favourable – open-minded, incredibly hard-working, absolutely committed to being a little better every day … a master at using film,” wrote David Halberstam in his 2005 profile on Belichick, “The Education of a Coach.”Another great coach took note of that.Before Nick Saban started winning his five national college titles in college, he was Belichick’s defensive co-ordinator with the Browns from 1991-94.“I thought I knew something, and really found out that I was really in a position to learn a lot,” Saban said. “Like him? I attribute a lot of it to Bill Belichick.” Vince Lombardi had a well-earned reputation as a taskmaster, and yet one epiphany that took him over the top was the concept, virtually unheard of at the time, that the word “love” really did belong in a locker room.More recently, Tom Coughlin overdid discipline for most of his first 10 years in the NFL. When you connect with people, they’ll run through a wall for you.”Belichick, a people person? No, I didn’t like him.”Among the 15 blocks on Wooden’s famed pyramid of success is “self-control,” an attribute that applies to the players as well as the coaches and general managers choosing them.In a recent talk he gave to a group of coaches, Popovich spoke of the virtually mandatory requirement to resist talented players who are more focused on themselves than the team.“That’s not easy,” he said. Only years later did the Hall of Fame quarterback concede that he benefited from Noll’s coaching. “But great coaches, the first thing they do is connect. “I think every player really wants discipline. He values the team’s overall culture ahead of its individual parts.He rules his team with an iron fist, yet instills that team with a sense of family.He can appear heartless – quick to say “goodbye” to those who no longer fit in – yet he is deeply loyal.He has hard-and-fast ideas about how to run his own team, but is never against learning and adding bits of others’ expertise to his own repertoire. And they want to win. Of course I did,” Bradshaw said last year. Yes, this is a description of New England coach Bill Belichick, who can set himself apart Sunday by winning a record fifth Super Bowl title as a head coach. “You have to follow through, be good to your principles. “Did I respect him?
