IMHO,
NBC:
Notre Dame - despise
Minor League Soccer - despise
French bicyle racing - despise
Olympics "sports" (subjectivly judged circus tricks) - despise
NHL - love
Indy Car - like, but going bankrupt again as it has lost its way, again.
Other hockey - like
Sports talk - great potential, but so far poorly executed
CBS:
Mid-major college football - like/love
College baseball - like
minor college sports - disinterested
Lacrosse - disinterested
lack of sports news or talk - unacceptable
Both, IMHO, need to get some rights to some more sports. But, as of now, NBC is deeper.
The first thing CBS should get is the secondary rights to its own Masters Tournament from ESPN.
