Of course it's not a liability issue. I never said it was. I said that was the excuse used for years, and it was bogus. It was money that spoke, and money will continue to speak.
There's a reason the NCAA basketball tourney more than doubled in size. It's called money, and more for average schools to share. It's what keeps some of them "somewhat" competitive.
I remember the old NHL real well. Six teams. Imagine playing each team in your league 14 to 16 times every season. To be honest, it was the same rodeo over and over again.
They advanced from the old playoff format when they added more teams. The more they added, the deeper they went with playoff teams. The same should apply to college football.
Now, don't split hairs over number of games or any of that crap on the issue. Look at it from the money spread across the board to teams that are barely holding their programs together. The objective is to keep them alive, not bury them under the weight of the handful of teams who make money.
Of course there's logistics problems with where you play your games in the playoffs. The same thing applies to basketball. You find ways to overcome some of those problems, and as I've heard people say out here, it's not the seats filled in the stands, it's all about the TV bucks. Now that's forgotten? Please!
I like to look at the underside of some of these issues. I've always done that. Like the issue of Vegas getting an NFL team, and the Chargers moving to LA. I saw both happening, and talked to people who told me to quit listening to the BS being put out there, because both were going to happen. I was told I was nuts, didn't know what I was talking about, and well.... it don't make any difference. Guess what? The guy was right. Vegas and LA. Just like called.
He happens to be the same guy who I've discussed NCAA tourney formats with for football. He stated you could still place games effectively by having the top rated team for the first two rounds play home games, to insure that there'd at least be a stadium pretty much full of people. After that, go ahead and use advanced locations, just like they do now. Seems simple enough. Of course this would be wrong, but so was Vegas.
And by the way, as an adder, People might be surprised where the Raiders will land for next year, if they don't have Vegas digs until the following year. Of course, as I'd be told, "It will never happen. They can't support a team."
