Lee was a fine offensive addition to the Pens and was a key playmaker on the powerplay. He reached the 30-goal mark twice and scored a personal best 64 points in 1980–81 playing on a line with Greg Malone and Rod Schutt. Unfortunately, the Penguins were not a successful team at that time, and Lee only played 19 playoff games during his five and a half years with the organization. He finished his NHL career with 245 points in 431 games.
