Component/program for downloading data/statistics from the web?

There must be lots of these things, tailored to particular data sets (e.g., stock prices). I have a very specific data type in mind:

The data I want to downloard are NFL statistics (those that reflect performance, e.g., total yardage gained/allowed,etc.) by team. I'm thinking about developing a program that takes that data and, via regression analysis, predicts the point-spreads each week. I can handle the regression analysis, and the design of the program that would do the predicting, but I'm at a loss on how to get the required data (updated each week) into the program.

The simplest option would be to force the user to enter the data (into a local database) manually, and put the burden of getting the data on the user. I would like to automate that process.

If anyone knows of a program that does this (predicts NFL point-spreads), I'd appreciate hearing about it. I mean, of course, a program that is statistically sound -- not just a reflection of the "experts" flapping their gums.
