"Sigge" was a fan favorite who played his entire career (1925-1939) with Hammarby IF, winning four Swedish championship titles. He was known for his physical play. He loved to bowl over an opponent to take the puck or attempt to carry the puck right through the defender. With his speed and size he was able to catch many opponents by surprise. He liked to shoot first and think later.
Oberg represented Sweden internationally 31 times, including at the 1928 Olympics where they won a silver medal.
Sadly this great sportsman met an early demise. In April of 1949 police found the body of 42 year old Oberg drowned in a possible suicide.
