downloading nfl rosters to xbox 360 hard drive using transfer cable

That wouldn't be possible. The data transfer cable is only meant to move data between 360 hard drives in the event that you get a new one. Xbox data is not meant to be seen by a PC and transferred between the 2 so you wouldn't be able to get anything from
the PC into a 360 game without violating the terms of service.

There is a new version of the Transfer Cable that does work with the 360 S hard drives. For more information:

Hi there - the new Xbox 360 S model uses a different type of hard drive, so your old hard drive will not attach to it. We typically recommend the 250GB model if you like to play online and purchase content a lot, but the 4GB model is great if you prefer
to play locally or you don't purchase or download content. You can transfer all of your old data via the Xbox 360 Transfer Cable, available here:
