Let's revisit this. Both Tanti and McBain played for the Canucks in the team's 20th season (see patch). Both wore #9. However, McBain was a right hand shot while Tanti is a left as portrayed in tho photo.
I believe you are right. Garth Butcher wearing #3 is the clue. He only wore that number for 6 games. 5 regular season games in 81-82 and the final playoff game v the Islanders. Molin was on that team and wore 26.
