Prior to the 1970–71 season, Charles O. Finley, the flamboyant owner of baseball's Oakland Athletics, purchased the Seals.[3] Finley and Roller Derby boss Jerry Seltzer had both put in a bid on the team. Although Seltzer's offer was slightly better and included a more detailed plan for revival, a majority of NHL owners from the "old establishment" voted in favor of Finley.[4] General manager Bill Torrey left by mid-season due to clashes with Finley.[5]
On October 15, 1970, with the new season already two games old, Finley announced that the team's name was being changed to California Golden Seals[6] ("Bay Area Seals" had been reported the previous week, and appears on some of that year's promotional material), following a number of other marketing gimmicks intended to sell the team to the fans, among them changing the Seals' colors to green and gold to match those of the popular A's. The team's uniform crest was now the word "Seals" in a unique typeface, but an alternate logo using a sketch based on a photo of star player Carol Vadnais was used on marketing materials such as pennants, stickers and team programs. The original 1967 California Seals logo recolored in green and gold was often seen on trading cards and other unofficial material, but was never adopted by the team. The Seals are remembered for wearing white skates, but initially Torrey convinced Finley to use green and gold painted skates instead, as team colored skates were a trend of the period.[5] However, this was all for naught, as the Seals finished with the worst record in the NHL that year. On May 22, 1970, the Seals traded their pick in the first round of the 1971 NHL Amateur Draft to the Montreal Canadiens along with François Lacombe in return for Montreal's first round pick in the 1970 Draft (Seals selected Chris Oddleifson), Ernie Hicke, and cash.[7] As a result of the Seals' dreadful season, the Canadiens had the top pick in the 1971 Draft, and used it to select future Hall of Famer Guy Lafleur. This transaction now ranks as one of the most one-sided deals in NHL history.[8]
