Secondly, in all seriousness... While pretty, they are quite hard to make any actual use of. Things that should be compared are far from each other and oriented differently making them difficult to compare. Trends are hard to notice because everything is so widely spaced. The losing team score is too faint so it fades from the vision.
But yes, it is pretty.
Of course, you're stuck as to what to call American Football, because handball is now a completely different sport that is popular in central europe, but never really cracked the anglosphere.
Completely off-topic, I know, but interesting nonetheless. There's probably some analogy that can be drawn here between common names for things and the various display ports that are used and fail to be standardised upon, but I am too tired to find it :-)
Good point with regard to the trends being hard to spot because the games are laid out by kickoff date/time. I may add a toggle to turn that on/off which should make trends easier to spot.
I didn't test on many displays so it's possible that the losing opacity is too light on some displays.

I would love to see the teams closer together to get a quicker sense of comparison. The nice thing about d3 is it makes it fairly easy to add interaction, so giving the user an option to re-layout would be a cool addition.
