#1: Fuller needs the ball to feet
With his 6ft 3in frame and powerful physique, the temptation to fire long balls into the chest of Ricardo Fuller is understandable.
And more often than not, that is what Millwall have done this season. He's big, strong and wins his fair share of headers.
Lee Gregory certainly benefited from having more scraps to feed off against Wolves.
But the three goals Fuller has scored for the Lions prove that he needs a very different kind of service to be his most effective in the box.
Against Reading, Scott Malone fed a pass into the striker's feet and he controlled expertly before curling a shot into the bottom corner.
The Jamaican was on target twice on Saturday and in both instances the ball came to him on the deck.
His first goal was rattled in after Scott McDonald's clever knock-down in the box. The second was the result of a brilliant first touch, followed by a thumping drive inside the near post.
Rather than ask Fuller to run the channels or win flick-ons, Millwall need to keep giving him the ball – and let him do the rest.
#2: Martin makes big impact on injury return
Lee Martin was only on the pitch for 35 minutes but in that time he made more tackles and put in more crosses than any other Millwall player on the day.
What that shows is what we already knew – that Martin gives the Lions a natural outlet on the wing and is fundamental to their pressing game.
His ability to win the ball back high up the field is something that Millwall have desperately lacked during his injury lay-off.
Martin's energy was a major contributing factor to the Lions' stunning comeback from 3-0 down, so ensuring that he stays fit is absolutely vital.
To be on the safe side, Holloway may again use the 27-year-old off the bench against Wigan tomorrow night because losing Martin to the treatment room would be disastrous.
Millwall shouldn't be so reliant on one player for so much of their attacking impetus, but the reality is that they are significantly worse off without Martin.
#3: Malone could be an option on the wing
While Martin finds his feet again after a month on the sidelines, Holloway should consider giving Scott Malone a starting role on the wing.
Like Martin, Malone gave the Lions much-needed running power when he came off the bench at the weekend.
His speed and direct style caused former club Wolves all sorts of problems.
With Matthew Briggs currently Holloway's preferred choice at left back, there is a strong case to be made for playing Malone further forward.
Millwall need pace on the counter attack – especially away from home at Wigan tomorrow – and Malone can carry the ball into dangerous areas.
He has the legs and the skill to do damage in the final third. In the short term at least, Malone could be the ideal stop-gap on the wing.
#4: Lions need a settled back four
Andy Wilkinson's imminent arrival from Stoke City should solve a lot of Millwall's problems.
Four different players – Alan Dunne, Jimmy Abdou, Richard Chaplow and Lee Martin – filled in at right back during the course of Saturday's draw with Wolves.
That meant there was constant reshuffling in the back four and uncertainity about who was marking who at set pieces.
With Wilkinson coming in on a 93-day loan deal, Holloway will now be able to pick players in their correct positions without having to move them around.
Wilkinson, however, won't be a like-for-like replacement for the injured Carlos Edwards.
Edwards has been a massive loss for the Lions – in the 16 games he has played for the club, Millwall have lost only three of them. But he is irrepelaceable – a one-off.
The 35-year-old is unique in that he is a winger who has been succesfully converted into a very effective defender.
Few players make that kind of transition permanently, without at some point reverting to their previous position.
But Wilkinson, who has played over 100 games in the Premier League for the Stoke, is a no-nonsense bruiser who will bring experience and leadership to the defence.
And most importantly, Millwall can now get some continuity going in the back four.
#5: Gregory's movement is Harris-esque
Lee Gregory looked the part on Saturday.
As he spoke to the written press after the game, you could tell that the striker is brimming with confidence now that he has opened his account for Millwall.
He scored his second goal for the club against Wolves with an ice-cool finish that belied his non-league pedigree, showing the composure of a Championship forward.
But what really stood out was Gregory's movement.
He was constantly on the shoulder of the last man, making runs in behind defenders and waiting to pounce on any mistakes in the back four.
The goal was made by his run. And when Shaun Williams picked him out with a clipped pass, the 26-year-old made no mistake.
It's a big compliment, but the way Gregory finds space and anticipates a pass is reminicsent of Neil Harris's predatory instincts.
