Ultimate Frisbee combines the greatest aspects of American football, soccer, basketball, and everyone's favorite beach sport: Frisbee disc tossing. Ultimate, on the other hand, is everything but leisurely. A good game of ultimate frisbee is unlike any other. It's fierce, fast-paced, and tactical. It requires quick decisions and split seconds of hesitation can mean the difference between a victory and a loss. The first thing you need to know about playing ultimate is that it's not hard. Yes, you'll get bruised up during games, but there are no major injuries that come with this sport. The most common injury is to the knee, which can be caused by someone jumping into the fray too quickly or making an aggressive move toward the end zone. There are several types of ultimate players: defenders, mids, and attackers. At first glance, these roles might seem obvious but they each have their own specific skills that make them valuable additions to any team. For example, defenders are usually very fast and strong individuals who like to stick with one player all game long so they can protect him or her from getting beat down by more powerful opponents. Mids are typically bigger players who like to take on multiple opponents at once. They're usually found as centers on traditional American football teams or forwards on rugby clubs. They have the ability to use their size to their advantage by knocking the ball away from opponents or even bringing it in for a quick score.
