I care that there is an opportunity. Sure - most G5's champions are going to lose to most P5 champions. I don't disagree. But there may be one who wins! Sure - it will be difficult for a G5 champion to win multiple games, get to the championship game, and win that too. But guess what - there will be 10 other teams who will also lose prior to winning a championship.
What I don't like is the assumption that because they are most likely going to win, they just shouldn't even play the game. That's wrong thinking in my book.
