I felt that this would be good to tell the community here as the NFL 2K series seems highly regarded. Also, this news is about a year old, but I didn't see any mention of it around here.
If you're interested in doing this, the most simple way to go about doing it is buying a DreamPI kit available in the
Dreamcast Live store and a copy of the Dreamcast web browser/Quake III. Afterwards, you can follow a tutorial at either of the below links.

If you wish to save some money, you could also buy the parts from the kit separately at other places like Amazon (for the USB modem
Dell NW147/Lenovo RD02-D400 will work best) and flash an image for Dreampi 1.7 on your own.
For more info or troubleshooting questions you can ask here or if I don't know, you can get help at the Dreamcast talk forums or you can look through troubleshooting on the Dreamcast Live website.
