A few years ago there was a series of commercials for McDonald’s that ran over here in the States where Larry Bird and Michael Jordan played a game of horse for a Big Mac. The first commercial featured the two retired NBA players proposing increasingly more preposterous shots for the other to take, culminating in a shot from the roof of the Hancock Center and with Jordan uttering the catch phrase “nothing but net.” As far as commercials go, it was goofy and kind of boring but what it did well is play on the mythology of both Bird and Jordan as two of the NBA’s all-time clutch shooters.
Of course, the commercial only works because it’s a wink and a nod to that mythology. We all know that Larry Bird can’t make a shot from outside the stadium, through an open window, off the wall, off the billboard and get nothing but net. That shot would require backboard.
It’s that mythology of sports stars that has always fascinated me and makes me wonder if heroes of the past like Hercules or Goliath weren’t just the Michael Jordan’s of their day: the stories of their feats of strength passed down from generation to generation and magnified to create a mythology of the god-like powers they possessed. I can only imagine the stories they will tell of Michael Jordan in 1000 years. Perhaps he will be some sort of giant slayer, dunking on the 16 foot tall Patrick Ewing with the jawbone of an ass — Charles Barkley.
Arsenal’s pantheon of heroes is long and varied as well. I recently heard someone call Ian Wright “the most clinical finisher ever” or something to that effect. And for many who harken back to a time when Arsenal played the best defense the world has ever seen, there’s Tony Adams, who never missed a header and kept 39 clean sheets in one 38 game season.
Current players get this treatment as well, sometimes deserved and sometimes not. One good header in an important game sets an impression that a player is good in the air just as four goals in a game can set the myth that a player is “one of the most technically gifted players ever to play for Arsenal.”
Usually, the false idols are found out over time and those with true stature in the game perform consistently. Or as they say in England, form is temporary, class is permanent.
One player who has shown a great streak of form for Arsenal this season is Laurent Koscielny.Tied with Stoke City in 7th, Arsenal’s defense is one of the worst in England at the moment and yet Arsenal supporters should take solace in the work that Koscielny is putting in for the team. Among active players, Koz leads Arsenal in interceptions per game, clearances, offsides won, and in the category that most vexed Arsenal over the last three to four years; aerial duels.
That said, his numbers rank low in comparison to someone like, say Gary Cahill. In aerial duels, Gary Cahill is 7th in the Premier League having won 63 duels in 19 games while Koz is much further down the list with just 42 duels won in 20 matches. Clearly Cahill is better in the air than Koz, right?
Uhhh… no.
One thing we know about Arsenal is that they try to keep possession. This results in fewer chances for the opposition to put the Arsenal defense under pressure and subsequently lower raw numbers in most defensive categories like “total aerial duels”. That’s one reason why I like to look instead at percentage, in which case you would see that Koz is winning a respectable 68% of his duels and Cahill is much further down at 61%.
This fact that Koz is winning 68% of his aerial duels compared to 61% by Cahill intrigued me. What percentage are his teammates winning? What percentage are players on comparable teams to Arsenal, in terms of possession, winning? What about other numbers? What about last season, how does this compare?
First, what I did was take the top four possession-based teams: Arsenal, Man City, Chelsea, and Swansea. Then I sorted their player lineups on WhoScored.com by aerial duels won per game and took the top three defenders. Thinking that I wanted a bigger picture of data about headers I also went and included clearances in there as well. Put it all in a spread sheet, color coded by team (red and white for Arsenal, blue and white for Chelsea, light blue for Man City, and white on black for Swansea), and then sorted by percent of aerial duels won. This is that chart:

Ok, so I included Santos because all of his numbers are extraordinary but ignore him for the moment. The top of table shows what I think you’ll all agree is “common sense.” That is to say, John Terry is widely considered a good defender in the air and Arsenal’s defenders are down at the bottom along with Swansea.
Still, Kozscielny’s numbers are pretty good. In fact, if you look at last season compared to this season you’ll see that Koz has markedly improved in his percentage of headers won from 53% to 68%:

Whereas his aerial duel numbers are up, Koscielny’s clearances numbers are down slightly but he’s still tops of the Arsenal team in that number with 114 or 5.7 per game.
The numbers below Koz are what’s worrying for me. Mertesacker has gone from a player who won 74% of his aerial duels in the Bundesliga to a player who is winning just 57% of his aerial duels for Arsenal. That said, this is his first season in the Premier League and as such, just like Koscielny needed a season to bed in, it’s too early to call time on Mertesacker. If he can get that number up to 62% or so, around where Cahill has been for the last two years, that would be a good turnaround for the season and something to build on for next year.
But it’s Vermaelen that is most worrying. I have no doubt that common sense says that Vermaelen is Arsenal’s best aerial defender. But having written about him for nearly three years now I am not at all surprised that his duel percentage is just 55%. He’s not as good in the air as everyone thinks.
Now, before you say “yeah, but he plays at left back!” Look at the chart, there’s a reason I included Santos and Gibbs: their numbers are almost an exact copy of Vermaelen, except that Santos is some kind of bad ass (more in a second) in the air whereas Vermaelen and Gibbs are kind of “meh.”
Where I think that pair deserve some credit is in the fact that they try to get stuck in. Their aerial duels attempted per game numbers (ADA/G) are very respectable when you look at someone like Djourou who has just 17 duels in 14 matches.
And finally, a bit of a non-sequiter, take a look at the Arsenal defensive numbers for the season and you will see just how badly Santos and Sagna are missed. Santos only played 8 League games but in those 8 games he managed to lead Arsenal in tackles, interceptions, and place third in aerial duels won per game while winning nearly 90% of those challenges. Oh, and in the category of average passes per game, Santos was 4th on the team with 61. Meanwhile, Sagna only played 6 League matches for Arsenal but amassed 12 tackles, 15 interceptions, and just one foul.
Arsenal have their fair share of myths, some rightly earned and some not so rightly earned. Under the duress of playing for an Arsenal side that is largely disorganized defensively, under constant aerial bombardment, and in a rebuilding season in both midfield and defense, Koscielny has earned a bit of a mythical status for me this season.
It may also turn out that it’s not the 2-1 loss to Man U that was the mythical turning point for Arsenal in 2011-2012, but rather the 3-1 loss to Olympiakos. Because that was the match in which St. Andre was injured.
