ET: (Expansion Topic) Non-revenue sports

This is somewhat directed at FormerlyAnonymous:  What kind of ramifications do expansions have on non-revenue sports?  I'm thinking about baseball and the future of the conference, and I have to believe that Nebraska would help out baseball.  Would Wisconsin finally field a varsity team?  What about if we head east and pick up Syracuse, would Michigan push lacrosse into the varsity status?  Would we want all sports that currently play in a non-Big-Ten league (hockey, lacrosse, etc.) to build a conference, even if it means fielding teams that aren't necessarily competitive at first?  Discuss.
