F or people coming from other team sports where the players are mixed on the field (not volleyball or baseball), the biggest adjustment is the playing style that you talk about. No double teaming the thrower, no straddling the thrower's pivot leg, and other rules that you should learn (there aren't many). You also have to watch for people who take advantage of the rules (e.g. taking that third step after the catch so you can clear the defender). You also need to change some of your instincts - if you are back on a 2-on-1 you can ignore the guy who catches the disc because he isn't going anywhere - you need to stay with the free runner until you get some help. It is self-refereed and most guys honor the rules. The physical part is usually in the end zones when you have multiple players vying for the final catch/defend. That's where you get a lot of collisions and also get to show off your ballerina moves. And yes, gratuitous diving to make catches is a badge of honor.
