#1: Carlos Edwards is 35 going on 25
It's quite astonishing that there was no place for Carlos Edwards in Ipswich's team.
The man oozes class, composure and confidence and the Lions have not lost a game since he arrived at the club in March last season.
When Edwards first moved to The Den, some questioned what impact a 35-year-old winger could have on a relegation-threatened side.
But those doubters were emphatically silenced as the Trinidadian inspired an eight-game unbeaten to help keep Millwall in the division – after making the right back berth his own.
And Edwards' superb form has continued into the new season. He's been a contender for man of the match in both the win over Leeds and yesterday's triumph at Craven Cottage.
Against Fulham, the veteran marshalled 18-year-old Wales star George Williams in the first half.
In the second, Edwards actually made his first ever mistake in a Lions shirt when he was dispossessed inside his own area – but his teammates were able to rescue the situation.
And that was only fair, because Edwards has got Millwall off the hook time and time again.
You would never guess he turns 36 in October.
#2: Shaun Williams is central to Holloway's system
If there was one player Ian Holloway could clone, he might pick Shaun Williams.
Williams' range and accuracy of passing makes him the perfect midfield lynchpin. And now that Nicky Bailey is injury-free again, Ollie is spoilt for choice in that department.
A £250,000-buy from MK Dons, Williams sees more of the ball than any other Millwall player – he always wants it, even under pressure, and you can trust him to pass to a blue shirt.
The 27-year-old is neat and tidy, keeps possession ticking over with his short, snappy distribution, but equally he isn't afraid to hit the Hollywood pass when he sees an opening.
Unsurprisingly, the best single pass of yesterday's game belonged to Williams.
Midway through the first half, he nonchalantly struck a bouncing ball with the outside of his boot to switch the play from right to left, finding Scott Malone on the opposite flank.
Fulham's midfield maestro Scott Parker would have been proud of that one.
#3: Martyn Woolford won't be a one-season wonder
Martyn Woolford surprised everyone last year when he top-scored for Millwall with nine goals.
But in falling one short of double figures, the winger lost a wager with a family friend – so he is doubly determined to reach the ten-goal mark this time around.
And he's made the perfect start after opening his account for the season with the winner against Fulham, a composed back-post finish following a brilliant cross from Ricardo Fuller.
Holloway yesterday described Woolford as "one of the best professionals I've ever worked with" and that's no surprise given the 28-year-old's relentless work rate.
Woolford runs harder and for longer than anyone else, and says he feels fitter and sharper than he did last year.
So don't bet against the midfielder leading the scoring charts again – because he won't be a one-season wonder.
#4: Fitness and resilience were crucial
Watching Millwall hang on to a one-goal lead has always been nerve-wracking.
But yesterday the Lions out-lasted a Fulham team that has been drilled by the infamous Felix Magath, a manager renowned for his gruelling fitness training.
Holloway's side used every drop of energy at Craven Cottage to ensure they got the points and demonstrated terrific resilience in the second half as Fulham pushed for an equaliser.
Last season, Millwall consistently found themselves on the wrong side of narrow margins – be it a a disallowed goal, a dodgy penalty decision or a wonder strike from the opposition.
So contrast Saturday's rearguard action with the draw against Blackburn in March, when the Lions twice conceded to ten men, and you'll see the huge progress that's being made.
Albeit against League Two Wycombe in midweek, Millwall got the job done despite playing the final half an hour a man light following Matthew Briggs' red card.
Millwall occasionally panicked at Fulham, giving the ball away cheaply, but Carlos Edwards, Alan Dunne, Mark Beevers, Scott Malone and David Forde were invincible at the back.
At the other end, Lee Martin and Scott McDonald were chasing down every ball.
In the past, the Lions might have crumbled under the pressure.
But Holloway has got them fitter and more resilient this season – and it's already paying dividends barely three games in.
#5: Fans and players are on the same page
For long spells last season, there was simply no connection or bond between Millwall's crowd and players.
Under Steve Lomas, the supporters couldn't recognise any of the traits that they have come to demand and expect of a Lions side over the years. There was no chemistry.
That has all changed. Over 4,000 fans made the trip to Craven Cottage on Saturday and they saw a genuine Millwall performance of fight and spirit, interspersed with moments of quality.
In the final 15 minutes, as Fulham came on strongly, the players and fans were feeding off each other, sharing their energy. Ian Holloway called it a "proud day" for the club.
And he said his players are "playing for the fans." It's showing, and the Den faithful now have a team they can identify with.
