Well I will respectfully disagree with you as well. I am not really a college football fan either and I think that is okay. However, if were a fan of say one NFL team, and hate golf, baseball, basketball, etc. then I am not really big sports fan, I just happen to like one thing. SPORTS is plural. In football, my team is the Titans and I also like the Colts (and I have been a fan since Bert Jones was quarterback so no I am not a front runner). However, I am always interested in what is going on throughout the league. I always follow scores from other games, watch highlights, and quite often watch at least some of other teams playing because I respect the league as a whole, and I want to know what is going on with say Alex Smith in San Francisco. If you are stuck, to only one sport or one team, a person doesn't have a large grasp of what is going on throughout the conference, league, etc. If, in your case, you are a Saints fan, you need to be concerned with what is going on with other teams in the division and the NFC.
Part of the problem the Memphis Grizzlies face is the announcers and fans have very limited knowledge about the NBA as a whole. There ought to be an NBA roundtable on Sports 56, etc. Fans need to become educated. It is how you build rivalries and gather enthusiasm when certain teams come to town. For instance, I was a big fan of the Utah Jazz when Stockton and Malone were there. When the Grizzlies came, I became a fan of theirs but I still follow the Jazz quite closely and get excited when they play each other.
The real sports fan can sit down and talk about things that happened in college football thirty years ago, the same for the NFL, NBA, etc. For example, I can tell you stuff about the NFL that occurred before I was even born. If all you have to say is "Do you think Tennessee can beat Florida this year?" Then your knowledge is limited.No offense to you sir. That's my personal take.
