Your link doesn't work for me. Forbes cites your 1/3 of revenue (which is very different than 1-to-3 ratio as you stated) here
http://www.forbes.com/sites/sportsmo...l-conferences/ but, as you can see, the ratio rises as the conferences get smaller. Once you get past those containing the 120 schools in D1 football, I'm going to guess basketball funds more than football does based on the NCAA shared revenue model.
If the BCS conferences kept all the Tourney revenue, as they should, the ratio would probably rise to 40% or so. (That wouldn't be even par with football, but it's in the ballpark). A 40-60 ratio of total revenue makes it fair to call the sports peers. We know basketball is important and makes lotsa money. If not, football schools wouldn't be throwing 2M+ salaries to guys like Lon Kruger, Frank Martin,Anthony Grant or Thad Matta.
