As long as they're selling enough tickets at premium prices on the primary market, I'm not convinced anyone making decisions gives a **** what they drop to on secondary sites.
For the bowls, and more importantly the cities that are hosting the bowls ticket sales are almost irrelevant.
What they care about is visitor count.
It wouldn't be that hard to put Georgia in Atlanta, ASU in Phoenix, etc. and they would probably sell out at a premium. That though wouldn't serve the real purposes of those host cities because most of those fans would drive to the game, watch the game, then drive home.
Instead of having 70,000 people in the stands they would rather have 20,000 people staying in hotels, eating in restaurants, shopping, and in general spending money.
Even a city like El Paso with the Sun Bowl. If they can get 15-20 thousand fans combined from the two schools flying in for the game it is a huge injection of cash into the economy.
The thing that makes it all viable though is TV paying enough for the game to pay the teams and the general operating cost of the game.
The real risk now is that with all the attention on the playoff, with the playoff rendering the games meaningless and star players opting out, will enough fans turn on their TV for the advertisers to be willing to pay for the games.
For a game like this Alabama-Michigan bowl I think it will still continue, footballs fans even if not focused on them will turn it on.
What is hard to see continuing are the games like the Arizona Bowl. Officially attendance was over 40,000 but hard to imagine that a lot of fans of either CSU or Miami (OH) travelled to see it, they don't even go watch those teams play when they are at home. Title sponsor is Snoop Dogg's Gin and Juice, again not a high budget product. And the game on the CW Network it's hard to belive that the TV money even covered the cost.
Even worse are games like the IS4S Salute to Veterans Bowl on Dec 14 in Montgomery Alabama. Official attendance was a bit over 12,000 which is not surprising. Western Michigan and South Alabama don't have giant fan bases. For South Alabama it is a day trip and they didn't show up. As ugly as Western Michigan can be in December not a lot are going to take time off from work and spend their vacation money to go to Montgomery. That isn't exactly on most peoples vacation bucket list. As well neither team is going to inspire many people to turn on their TV sets.
Don't think that the non-playoff bowls are going away anytime soon but as it stands now it's hard to see all of the current bowls continuing. I used to think that we needed to start by eliminating 3-4 of the bowl games, now it might make more sense to get rid of at leat 5 or 6 of them amd maybe more.
This will probably mean that some 6 or even 7 win teams from G5 conferences stay home but the eventual shakeout of big time college football is going to deal with many of these programs anyways.
