Don't know if it was posted yet but its an interesting video all the less http://www.whoateallthepies.tv/videos/116107/the-championship-table-minute-by-minute-video.html
Fantastic! Really shows how important our late goals have been this season (in fact, how important late goals are in general) and how important it is to keep working until the final whistle.
i found the graph linked under the video easier to follow as it wasn't changing every second so i could look at it properly. anyway, look where reading would be if every game finished at 60 minutes.
In conclusion, Portsmouth are apparently rubbish in the last 20 minutes or so of a game. Sounds about right.
