That's all well and good, but HS games are drawing large attendance for big games as well. At the same time this is an article about the highest attendance figures in history. Some of these high attendance games wouldn't be enough to stay above the required average to stay in Div 1 A football (15,000). I know, not a fair comparison.
I think another thing clear in the article is that baseball is bigger in the south than it is in the north. The phenomenom is largely regional, I knew this before. Miami of Ohio has a great hockey team and I've heard the games do quite well as far as attendance goes. While it may be a major sport at Miami it is not a major sport nationally. I'd say the same goes for Baseball. It may mean something at some schools, or maybe even in all of the south, but it won't catch on nationally like football, or basketball has.
Another thing, kinda branching out here, but I would even go as far to say that Women's basketball is bigger than baseball at the college level. I only judge that based on the amount of TV play the sports get. While baseball will get the playoffs on TV, I don't think I've ever seen a regular season game on TV. Women's bb however is shown through the regular season. Which is another point; Joining the Big East will be good for UC Women's Basketball. It is a very strong conference for wbb.
At any rate here's some interesting links. I think the most interesting thing in this whole mess is that Baseball is very regional. Looking at the top attendances the south is obviously the largest baseball area. Also you can see how similar attendances are for the top women's bb teams are to baseball teams as far as individual teams go while baseball has double the amount of games. The total season attendance for baseball is strangely missing.
