Since the severity of Rio Ferdinand's muscular complaints first began to surface in 2008, Evans has gradually edged further up the Red Devils hierarchy.
By last season, former manager Sir Alex Ferguson said he regarded Evans as a first-choice member of his side, with Ferdinand or Nemanja Vidic his partner depending upon the opponent.
Yet, with Phil Jones also earmarked for a central defensive slot and Chris Smalling good enough to play for England in that position, Evans accepts he can take nothing for granted.
And, speaking during United's current tour of the Far East and Australia, the Northern Ireland international outlined the work that has to be done to remain in contention at Old Trafford.
"For me, the last couple of years has been about learning how to live right off the pitch," he said.
"My focus has been solely about football. When I wake up in the morning it is the first thing I think about.
"I take time and think about how I am going to improve.
"It becomes an obsession. I get up two hours earlier than I used to. I get into training earlier and go to the gym.
"I understand there is a fine line. I like to play golf. I like to spend time with my wife. I don't overkill it. As soon as I have finished training I try and relax.
"But I have a routine which I have worked hard at and which works for me."
Evans recoils slightly when it is mentioned such focus is similar to that of former team-mate Gary Neville.
Yet single-mindedness and dedication are traits to be admired in an era where so many players are prepared to settle for something less than their best because the trappings of stardom have already arrived.
"The way I look at it is if I didn't do that stuff I might not still be at Manchester United," he said.
"When I see people working hard and putting the effort in I think 'fair play'.
"Others might think it is being busy or you are doing stupid work but it gives you a mental edge."
Never has that approach been needed more than this season, when United's squad are having to adjust to seismic change.
Prior to this summer there had never been a point in Evans' entire life when Ferguson was not United manager.
As a fan of the game it has taken some getting used to. As a player it brings an element of the unknown.
For instance, Ferguson's way of managing his squad was not only to ensure everyone got games, but those matches were meaningful, so, with the odd exception, a team selection could not be predicted.
"Unless it was Robin van Persie or Cristiano Ronaldo when he was here, there was never a first choice in any position," said Evans.
"If you didn't perform he would have you out of the team, but then if one of the other players had a game or two when they weren't at their best the manager would have no problem putting you back in.
"The key thing was whenever he picked a team you always thought he was doing it for a reason, not because of any personal vendetta or that he didn't rate you.
"Now we don't know how the new manager will work. That is why everyone is so desperate to impress."
Reports from a number of sources that the players are enjoying their work under Moyes are significant.
For, as Evans testifies, it will take the entire group to manage the transition, not one part of it.
"It all has to come together," said Evans.
"The players have to buy into what the manager is doing.
"The players didn't just go out and win the league last season. We had the coaching staff, the manager, the masseurs, everyone.
"You are literally spending every single day together. You have that bond."
The start of Moyes' reign could not be much tougher, with those fixtures against Chelsea, Liverpool and Manchester City looming straight after an opening-day trip to Swansea.
It has been openly debated outside the club what pressure would be exerted on Moyes should those results go badly.
Evans offers a different perspective.
"Whenever we have had a batch of tough fixtures in the past we have done really well and come out of them in strong positions," he said.
"At Manchester United, you have to win every game, no matter what the opponent. That is the way it is here.
"Even if things don't go as planned it is still early in the season.
"We have been there before. We lost our first game against Everton last year and still won the league by 11 points."
