Bleh, at IU I've been running with Frisbee guys at the same time as Basketball guys were running - starters from our b-ball team that went to the final four. They ran about a mile and were beat, we did five miles and that was just our first run of two that day.
Ultimate Frisbee stresses different physical skills than Basketball. At the tournament level it's all about running, if you can't sprint for minutes on end, you will be scored on relentlessly.
I do agree that at the pickup game level, Basketball is much more physical and challenging than Ultimate, but that doesn't mean real games in both don't demand true athleticisim.
At any rate, I'm just saying that no one is going to like every sport they play. I'm sure you don't like it when people try to write off basketball as a crappy sport by saing it's all about being abnormaly tall. People who play Frisbee like their sport and are serious about it, just like people who play Basketball.
