Is there any way to print stats and box scores and rosters from the websites without coping and pasting to another document?

Right-click (or CTRL-click on a Mac) in the box score or roster area, and select the option to "open frame in new window". You can then print just that frame of data without the team website borders. Some browsers even have a "Print frame" option when you right click inside the frame like that.
