Here's the thing:
lot of these sports are relatively very cheap. Track and field? If you've got a nice stadium, which we just built a brand new one, then your costs are almost nothing. Shoes, mainly.
You just need a good training facility and you're set.
Same exact thing with swiming & diving. We already have a top notch Aquatic Center and that's not changing. So it only costs you ... swim suits, caps, goggles, at that point. Peanuts.
BUT, this mainly makes sense if conferences for those sports are regional. Now suddenly you've got the track and field team at Stanford going to the Atlantic Coast to have track meets.
The swim team at UCLA going to Rutgers for a swim meet.
Because of football.
F'ing stupid
You have absolutely no idea what you're talking about, and it shows. So called "Olympic sports" largely not regional in how they compete. There might be a Conference Championship at the end of the season, and a Conference Champion may be crowned each year, but they are not competing head to head throughout the season like non-olympic sports do.
For example, here is the Men's Track and Field Schedule for this year:
Mar 2, Longhorn Invite (Outdoor), Austin, TX
Mar 15, Hurricane Invite, Coral Gables, FL
Mar 22, Clyde Hart Classic, Waco, TX
Mar 28, Raleigh Relays, Raleigh, NC
Apr 5, 44 Farms Team Invite, College Station, TX
Apr 5, Triton Classic, La Jolla, CA
Apr 6, Hamline Invite, St. Paul, MN
Apr 13, Bethel Invite, St. Paul, MN
Apr 17, Running On Hope Invite, Minneapolis, MN
Apr 18, Mt. SAC Relays/Brian Clay Invite, Torrance, CA
Apr 20, Alumni Gold, Baton Rouge, LA
Apr 20, Holst Invite, St. Paul, MN
Apr 24, Gary Wilson Invitational, Minneapolis, MN
Apr 25, Macalester College 5000m Invite, St. Paul, MN
Apr 25, Drake Relays, Des Moines, IA
Apr 27, Desert Heat , Tucson, AZ
Apr 27, Rider/Bolstorff Invite, St. Paul, MN
May 10, Big Ten Outdoor Championships, Ann Arbor, MI
May 22, NCAA West Regional, Fayetteville, AR
Jun 5, NCAA Outdoor Championships, Eugene, OR
So that's trips to Texas, Florida, North Carolina, California, Louisiana, Iowa, Arizona, Michigan, Arkansas, and Oregon for the Men's Track and Field team, all before any of the conference realignment stuff goes into affect. Albeit, not every invite has every sport, so it isn't the full track and field team traveling to every single one of these meets.
How about you actually look up the sports and how their scheduling works before you make claims about how they are effected by the conference realignment.
