I just compared the lag time on the link I posted earlier with the games today and the diff between the game and the link is only about 30 seconds wich translates to ONE play, if that.
the link posted is only for the NFL but all you have to do is scroll to the bottom and click on "ESPN" and it will take you to the main page with all the scores of all major sports.
Here is the link to the main page: http://proxy.espn.go.com/wireless/espn/wml/index
College Foot Ball
Mens College BB
Womens College BB
and those are just the head listings and there is more in each one. ALL this at pretty close to real time.
