Using rosters in teambuilder OD; can you delete a created dynasty

[Heyuimintojsus]

I was told that if we did a teambuilder online dynasty, all the names on a roster (like Luvtotha9s) would be used. The other league I started just used the roster - I wasn't prompted to pick anything if I remember right.

So I see no names but for the teambuilder teams. What's the deal?

And btw, can you delete a dynasty you created? I know you can in the save/load etc, but it still shows up on the online career page.
