This is so macro it’s not even the point.ND being CFP competitive is good for all of college football cuz it jacks up the ratings which is the basis for the price of the next TV contract. This topic has been discussed here ad nauseam. The effect on SU either way is so marginal that it's not worth the fuss.
CFB playoffs will get a huge contract no matter if ND makes it or Syracuse makes it.
College football is the second most popular sport in the country.
If the playoff rights go up for bid they will get a huge contract for either Fox, CBS, Turner if they left ESPN.
