Ask the players - the fans made a big difference in giving us home court advantage, and it was largely students who packed the gym. But then, that was another era, a different world, and we had better coaching.
In those days, the majority of the students were commuters and they still packed the games. I know I commuted each day from Manhattan and I remember not getting home some nights until 2 or 3 AM. Now, most of the students live on/near campus and don't have to travel home after a game. The bottom line is that it was a different ERA, with not so many distractions. No internet, cable channels, Ipods, e-mails, texting, etc. Life was simpler then.
Nevertheless, I think with intelligent marketing and promotion from the administration, the students could again become involved. But with this administration, I just don't see it.
