It's more about the expressions on their faces.
I did make a significant change to the underlying ratings system (LINK), which had some effect on the projections in that "program strength" could be affected. I'm also still incorporating actual rosters, juco guys, freshmen, etc -- that won't be fully complete for a few weeks. I do also make some manual adjustment to the playing time projections, which can affect the ratings as well. Feel free to let me know if you see any lineup projections, for Nebraska or anyone else, that are goofy.
I think Nebraska just sort of jiggled a few spots. But given that the projection for the Big Ten is so muddled, small jiggles can move them around in the projected conference order. To the extent you look at these at all, I think it's better to look at the overall rank and say this is projecting a bunch of Big Ten teams to be battling for tourney bids, Nebraska among them.
