“I used to be able to keep track of everything that was going on in the Ultimate World in the US pretty easily, just because we were small,” she said. “Now we’re just bigger, which is great. The sport is growing, at a tremendous pace, and I think that pro leagues will only help that.”

Besides being a rather new sport, Ultimate has no doubt struggled to gain the same acceptance that traditional sports hold based on its origins.

“I think because the sport was developed in the late 60s and first associated with the counter-community, it was branded as not a real sport,” Booth said. “But I think that has changed radically in the last 10 years.”

“Especially when I started 14 years ago before, the sport was not even growing at all, it was like, “Oh that's something you do with your dog,” Graham added. “People just really didn’t have an idea even if it was an individual sport, or a team sport. There is certainly a percentage of the population that doesn’t even know what it is.”

From youth camps to professionals, the recent efforts to spread this sport with hopefully change this going forward.

Between late-night practices and full-weekend tournaments, the Red Line represents Harvard in the Ultimate world, and does it well.

When the final whistle blew last week, the professional and amateurs shook hands. After a brief team meeting, the members of the home squad lined up, arm and arm facing the crowd of fans who came out to watch. In unison, the Red Line sang “10,000 Men of Harvard” as a ceremonial finish to the night.

In that moment, the crowd was reminded of a very important thing. No matter what marketing mechanics are used to spread the ultimate craze, it is the players themselves that make it all happen.
