Unpredictability
Unpredictability is what makes us love football but in Major League Soccer it goes a step further.
This season has been a tough one to predict. In the 2017 campaign a tremendous Toronto contingent became the first side in MLS history to win the domestic treble, taking the Canadian Championship, the Supporters' Shield and the MLS Cup in the same season. This term it has been a completely different story.
Stung by injuries to their front line, Toronto have already been eliminated from contention for the playoffs and have looked a shadow of their former selves.
Atlanta United, meanwhile, an expansion side in 2017 who were 14-points inferior to Toronto, have been unrelenting in their pursuit of the Supporters' Shield and have lost fewer matches than any other team this term.
Then comes the story of DC United. Hampered by the development of their new stadium Audi Park, they were forced to play 12 of their opening 14 matches away from home and found themselves at the foot of the table.
The arrival of Wayne Rooney from Everton and a string of wins in their new home venue and they are now in serious contention for a knockout berth.
