I've never done it before (didn't have Madden last year) but it was a BIG reason why I got both games this year. Also, I want to play with some of my star NCAA players... some of them deserve to be in the NFL and I want to see what their career turns out to be. If I can't import draft classes, NCAA 2004 might not get played much anymore.
Plus, what makes it worse is (as was stated above) there is already no online, and now EA screws us on the XBox draft classes? Conspiracy?
