I found this interesting. The following links are about as accurate as I can find online regarding the cap money spent by each team. The Saints' cap money does not include some of the recent signings, so it's probably about 3 million higher than the "bottom line" figure. I don't follow what the 9ers are doing that much, but their current figure is actually above the cap.
I am posting this because apparently the 9ers are in worse shape than the Saints, and a certain CB with the initials NA is currently having a debate with himself as to which team to join.
49ers:
San Francisco 49ers - 2013 Cap Hits
Saints:
New Orleans Saints - 2013 Cap Hits
According to these figures, the 9ers are actually above the cap by about 700K.
