My recollection was that Teambuilder and maybe even Madden 10's Online Franchise were "Beta" for a great long time, if they EVER changed them. I kind of assumed that they were done with it, but just used the word "beta" as an excuse for any flaws that were up there, and since it was the first year of the feature.
We're only in Week 2 of my 8-team Dynasty and I am noticing that things are slow to update. Also, we have no Week 1 stats. But for the people restarting, what good is that going to do? If it's broken, it will be broken when you restart also! So long as the correct stat information is available SOMEWHERE (like through the console), I guess I could live with it, but it was pretty easy to predict EA would have problems with this.
