Seattle SeaDogs
The Seattle SeaDogs played three seasons in the Continental Indoor Soccer League between 1993 and 1997. The CISL was a summertime league that attracted investment from a number of NBA franchise owners. The SeaDogs were backed by Seattle Sonics owner and billboard magnate Barry Ackerley. After two seasons of mediocrity, the SeaDogs won the final CISL championship in 1997. But the league closed its doors in December 1997 before the Seattleites could defend their title.
