I"m sorry if this is already somewhere on this thread.
When Sirius was in school did he play Quidditch and if so what position? I've read some stories where he was beater, but I'm not sure if that's canon or just authors choice.
It seems to me that playing Quidditch would fit with the big man on campus feel and we know his best friend James played. I just wanted to know if there is anything in books or interviews that verify that. Please help!
