All Toronto FC have to do is improve their ability to possess the ball and they will be a better team in no time. That is the simple logic that has been offered by many TFC observers. The question is, are they right; would increased possession lead to improved results?

Soccer Statistically did a post about the relation between possession and results in MLS back in 2011 and the results might have been surprising. They found that the average possession percentage for a winning team was 48.5% which means that the losing team actually held more of the ball on average. The short version was that back in 2011 possession did not equal results even when a team had more than 60% of the possession.

Have things changed in 2013 though? It seems likely that it will have considering that the top teams in MLS now seem to play a more possession based style than they did even two years ago, but will the numbers back that up?

First, here are the current standings in the MLS Supporters' Shield Race with no possession numbers factored in.

Now what would happen if we created a single MLS table built around possession. How much movement would take place if possession was what determined who belonged at the top of the table.

Team Possession Movement Sporting Kansas City 56.5% Up 4 Real Salt Lake 56.2% No Change Portland Timbers 55.4% Up 5 DC United 52.8% Up 15 LA Galaxy 51.6% Up 2 Houston Dynamo 51.5% Up 3 Seattle Sounders 51.2% Down 6 Montreal Impact 50.9% Down 4 Colorado Rapids 50.6% Down 3 New York Red Bulls 50.5% Down 7 San Jose Earthquakes 48.7% Up 3 FC Dallas 48.7% Down 2 Philadelphia Union 48.2% Down 1 Columbus Crew 48% Up 2 Vancouver Whitecaps 47.7% Down 2 New England Revolution 47.2% Down 1 Toronto FC 45.9% Up 1 Chicago Fire 44.4% Down 7 Chivas USA 44.3% Down 2

As you can see there is a lot of movement going on between the two tables, with several of the top teams in the Supporters' Shield race sliding down closer to the middle of the table, while DC United jumps up to near the top of the table in possession despite having an absolutely terrible record this season.

It is significant to note that despite all of the movement between the two tables, the top nine teams in the league all currently maintain a possession percentage over 50. Combine that with the fact the top nine teams in the league are in the top 10 in possession - DCU being the notable exception once again - and it starts to look like possession might just have something to do with getting results in this league in 2013.

So how do wins stack up when broken down by possession percentage for the winning team. The following two graphs divide the data into wins by the home team and by the away team.





As you can see from the home wins graph the majority of wins take place when the team has more than 50% of the possession. Even when the home team wins the game with less than 50% of the possession it is most frequently just below 50. There were just 24 home wins in the sampled data that came with the team controlling less than 45% of the possession.

When it comes to road winners the graph takes on a very different shape. In this case the majority of the wins come with less than 50% of the possession and very few teams have managed to win on the road while having 55% or more of the possession. Most of the winning teams on the road do it with between 40 and 50% possession which is the opposite for home winners.

If you take away the home/away factor here is how the graph would look:





The largest bar comes from the 50-55% range looking at all wins. When combined with the second largest bar (45-59%) it becomes clear that the majority of wins in MLS come with possession being fairly even. That is not much of a surprise as the majority of games have fairly even possession with one team slightly edging things so that means the majority of wins would be the same.

The one part of this graph that does jump out is the fact that there have been more wins this season by a team with less than 40% of the possession than there have been by a team with more that 60%. You would think that a team controlling the ball would be more likely to win the game, but it seems that when possession becomes that extreme the results become more unpredictable.

So is there a connection between possession and results in MLS this season? Well, when you consider that the majority of wins in MLS are by the home team the answer becomes yes. The majority of wins are by the home team and the majority of those wins come when they have more possession.

When you consider that Toronto is currently averaging just over 45% possession this season their struggle for results fits right with this data. In that possession range teams have only managed 36 wins in the entire 2013 season sample of 196 matches that resulted in a winner and a loser. That works out to just over 18% of the wins this season which is clearly not a great percentage.

It seems that if Toronto do want to be more competitive in MLS getting their average percentage up in the 2014 season would be a good start. This season the teams that are maintaining a possession percentage north of 50 are the ones that are winning the majority of matches. 48% of all wins this season have come to a team controlling more than 50% of the ball.

So if possession was not a good indicator of results back in 2011 it seems that has changed in the past two season. Now if you want to improve your odds of winning games a good place to start is by hanging onto the ball more. Just be careful of going over 60% of the possession because then things become far less predictable.
