Lemmerman is probably best remembered as the "2" in the 1-2 punch with Tom Wilkinson that Edmonton had at QB for most of the 1970s. Though if you look at the stats, Lemmerman was the "1" for a couple of those years. Lemmerman joined Edmonton in 1971, one year before Wilkingson. Lemmerman played seven games in his rookie season, sharing the QB duties with the less than memorable Don Trull and Larry Lawrence. In 1972, Wilkinson arrived in Edmonton, but Lemmerman was injured for most of the season, playing only 3 games. For the next five seasons, however, from 1973 to 1977, Lemmerman played in every Edmonton game, alternating at QB with Wilkinson. Lemmerman's best season came in 1976 when he had 354 attempts and 2271 yards passing. In 1978, Warren Moon joined Edmonton and the 1-2 punch now became Wilkinson and Moon, leaving Lemmerman out in the cold and he played only one game in 1978. After sitting out the 1979 season, Lemmerman made a one season, eight game comback, with Hamilton.
