At under 5'8", the compact player managed to become the Swedish national team's leading defenseman in the late 1960s and early 1970s because of his excellent skating skills and persistent training. His talent for choosing the right position, combined with effective bodychecking, made him a virtually impenetrable force to opposing forwards. At the same time, he managed to avoid foul play and behaved with the dignity befitting a true athlete.
During his career, Sjoberg played for the provincial Leksand, for Stockholm's Djurgarden and Gothenburg's Vastra Frolunda. At the 1974 World Championship in Finland, he was voted the best defenseman. That same year he turned professional, joining the WHA's Winnipeg Jets, where he spent six seasons. He was highly regarded in Canada and was the first Swedish hockey player to be elected a captain. In Winnipeg, they referred to him affectionately as "Professor" or "Little General." He was the captain of the Swedish team in the 1976 Canada Cup and was 75th on the "Great Men" list, playing 134 official games for Tre Kronor.
After he left hockey, Sjoberg became a successful businessman. In 1980 he returned to Sweden and settled in the old university town of Uppsala. Acting as the New York Rangers' overseas scout, Sjoberg recognized a future hockey star in a young, tall and awkward Kjell Samuelsson and promoted him in Canada despite the doubts of skeptics. Samuelsson went on to become one of the NHL's most enduring leading defensemen.
When Sjoberg died in 1987 at just 43, eulogies arrived in Uppsala from all over the world.
