I'm not sure, but hang on to that download just in case. At least on the PS3 version, if I hit triangle on the NCAA 14 logo in the XMB, one of the options there is "purchase". I did select it and it said there are no items to purchase at this time, BUT maybe when the actual game gets released, there will be an option to buy it from there and skip the download again.
Just a thought.
Edit: You're given the same option if you try to start up the Early Release now that the time has expired. I think it will really work once the game goes live on the PSN store without needing to download again.
