I've updated this post with the 1932-33 and 1933-34 teams.
All-star team selected by NHL coaches (1927 to 1941)
Comments:
1932-33
The writers had John Ross Roach as their first-team all star goaltender, and Charlie Gardiner on the second team. The coaches didn't have Roach on either team, instead they had Gardiner on their first team and Roy Worters on their second team.
The writers and coaches agreed on their four defencemen.
Up front, the coaches preferred Howie Morenz at first team centre, and the writers preferred Frank Boucher. They agreed on the wing choices for both teams.
1933-34
The coaches actually rated Earl Seibert the highest of any defenceman, while the writers didn't place him on an all-star team at all. This high rating by the coaches matches his high finish in Hart voting, but for some reason the writers couldn't find room for him on their all-star teams. The coaches demoted King Clancy to a second team spot, and Ivan Johnson dropped to 5th and out of an all-star spot.
The coaches and writers had the same goaltenders and the same forward line on the first team. On the second team, the coaches preferred Larry Aurie at 2nd team RW and the writers preferred Bill Cook.
