I think one answer lies in the fact that a football game is an entire day experience. You aren't just paying for the game. You are paying for the recall of the memories you made with you dad, your brother, your best friend. Tailgating, Volwalk, the Band marching to the Stadium. It is an entire event. And it only happens a handful of times a year. All on Saturdays, so people can make it there from out of town. And it is always sold out. And as a man who went to these games as a kid with his dad, then went as a student, an alum, a husband, and now a Dad, those memories are re-lived twice a year when I come in for games.
Baseball, well, baseball fans are used to having a lot of baseball games all week long for months. And, it is just the game. There is not the buildup, the anticipation, the drama and the pageantry. The stakes for individual games is rarely as high - if you lose tonight, you can still win the series. Many times, there are lots of empty seats. Fans have a hard time understanding how so many seats can be so empty, yet prices still be so high. So it goes..... I will say, if I lived within 90 minutes of LNS, you would not ever have the problem of a wasted ticket.

5+ hours? Well, that is a bit different.
I love Tennessee football. I rarely pay top dollar for tickets because I mooch off the family's 63 year history of season tickets. Once mom is gone, those tickets are, too, and I will very likely pay a premium for one game a year to enjoy the weekend with my bride.
Tennessee baseball? I am able to come in 1x a year for a high-dollar series (Fla., Ga, LSU), or maybe 2x a year if tickets are reasonable. I love Tennessee baseball games. I love them as much as I love the football games, often even more. But the total gameday experience? Football wins.
That said, this weekend's games are very reasonably priced. The product you are getting, against a rival opponent, in what can still be an electric environment, is every bit worth a $30-50 ticket. Wishing for a $12 ticket is just not realistic with the product on the field. Everyone who has complained about wanting to go to a big series, a meaningful series, at a reasonable price? Now is your chance. But those tickets and get ROWDY!!!!!
