The 1970BC Lions finished in fourth place in the Western Conference with a 6–10 record and failed to make the playoffs. New coach Jackie Parker had led the team to a 4–2 record in the final six games of 1969 after taking over for Jim Champion and there was reason for optimism after a 5–3 start to 1970. However, the wheels fell off in the fall as the Lions won only one game in the second half of the season.
Before the season, Empire Stadium became the first facility in Canada to have artificial playing surface installed, made by 3M, under the brand name "Tartan Turf".
Running back Jim Evenson had his third consecutive 1,000-yard season with 1003 yards in an injury-shortened 14 games and receiver Jim Young had 1041 yards receiving. The big offseason addition of Ottawa star Vic Washington was a bust as he played only 9 games and was openly disgruntled for most of season.[citation needed]
The Lions introduced a new jersey which featured orange "ti-cat" stripes down the arms of home and away jerseys. As well, the Lions went to grey pants which they would wear for the next eight seasons. The "BC" on the lion's cheek was black for only this season; all other seasons it was white because it showed up better on television.
After the season, Jackie Parker was promoted to general manager and he hired Eagle Keys away from Saskatchewan to become head coach of the Lions for the 1971 season.
