I also lament that conferences are less and less regionally based.
Sort of related to this: the sheer size of conferences now.
I was thinking this morning about how with 16 teams now and no discernible rotation so far, the schedules are more disparate than ever, and without divisions, I greatly struggle to remember who plays who.
There's always been games I didn't get the chance to watch, but prior to Texas and OU entering the league, I knew Vanderbilt played Kentucky at some point. I knew Ole Miss played Arkansas at some point. Etc., etc. It seems that just knowing about the schedules helped me retain the results better. So now I'm not even sure if those two example games happened this year, and it exacerbates my failure to remember much about league results. Granted, I've also mentioned my failure to remember much about LSU's schedule or the results.
But the point is I think I identified another facet of today's game that detracts another small piece that used to make it more enjoyable. I don't know who's playing who anymore. There's more conference games than ever to keep up with, so I'm missing a greater percentage of games, having only the time to watch the same amount as I used to, so I'm aware of less than I used to be. And I have no general knowledge--such as teams in the East and West who will all play each other--so the landscape of the SEC is that much more dizzying and out of focus for me.
I hope having the three "perma"-rivals will help with that. I won't be able to keep up with a lot of matches, but at least there will be a small handful of teams tied to other teams that will help me better recall the schedules, and thus remember results.
