Q Is For Quidditch

Ever since reading the first Harry Potter book I've always wanted to try this game. It's an extremely rough but very popular semi-contact sport, played by wizards and witches around the world. Matches are played between two teams of seven players riding flying broomsticks, using four balls and six elevated ring-shaped goals three on each side of the Quidditch pitch (field). In the Harry Potter universe, Quidditch holds a fervent following similar to the position that association football holds as a globally popular sport.

There are seven players on a team: three Chasers, two Beaters, one Keeper and one Seeker.
The Chasers progress up and down the pitch passing the Quaffle by hand amongst themselves while keeping it away from the other team, in an attempt to score goals by throwing it through one of their opponent's three goal hoops which scoring 10 points. In this respect, the game is similar, as Harry suggests in the first book, to "basketball on broomsticks with six hoops".
The Keeper will protect the three goal hoops, in much the same way as a goalkeeper in association football.
The Beaters are armed with wooden clubs that are similar to, but shorter than, baseball bats. They are tasked with protecting their team-mates and the seeker (mainly) from the Bludgers by knocking these balls off course or towards opponents.
Finally, the Seeker, usually the lightest member of the team and equipped with the fastest broom, is tasked for searching for and capturing The Golden Snitch. Seekers are the only players permitted to touch the Snitch. The seekers, like Harry Potter, are usually small, agile, and stealthy.
Each team includes a captain, who may play any of the four roles. The captain helps the team practice and chooses the team players after the tryouts.

I would definitely be a Chaser because I play a forward in soccer and I generally like being the guy who scores all the goals. That's just my style. It's not modest but it's true.

I'm dying to know which position you guys would play and why?
