It's cause they rolled it out for the start of football season where the WHOLE thing looks like this #$%$. Even your team page etc. At least we have our team page still looking good in baseball right now. Wait until they throw-up (a good description of what their graphics looks like) a baseball equivalent of the dark, blurry football imagine that is now the background of your team line-up page in football.
If they keep this graphic mess around we will be moving our leagues to some other site next season.
