Blip Or Trend?

Since the end of the 2007-08 season, the number of English Premier League matches finishing Under 2.5 goals has decreased each season. It's a trend that seems to be continuing, in fact accelerating, as you can see in the image above. If the percentage of Over 2.5 goals stays even close to 60% this season, and there is still more than half the season remaining, then that would be a significant shift from what is considered the norm. While more Overs is not good for draw-seekers, the XX Draw Selections have had 17 selections from England so far this season, 10 finishing under - better than the average 40%, but from a low sample it's impossible to draw any conclusions. As time permits, I'll take a look at the other leagues I follow and see if the EPL is an anomaly, but it's an interesting observation.
