... I don't quite know what to do with Lach's playoff resume. On one hand, and on surface, the numbers look good. Similar to his contemporary Kennedy (who is a great playoff performer), better than contemporary Sid Abel, and much better than another one of his contemporaries, Milt Schmidt. And he was a well rounded player too.
But then, there's a catch :
From 1943 to 1946 : 29 Games - 13 goals - 31 assists - 44 points
From 1949 to 1954 : 44 Games - 5 Goals - 14 assists - 19 points
Everyone has his own opinion of War + 1946 Numbers. And it's not like the Habs were an extremely successful team in the playoffs of the second group of years either, so it's not a case of a player sacrificing the numbers for the good of the team. And we're also talking about a playmaking center playing with Maurice Richard.
But then again, THIS reasoning is ... a bit simple. Between 1949 to 1954, Elmer Lach was 31 to 36 years old, off his prime (and suffered a serious injury in 1949, I think). Which mean that we have a case of a player whose prime (playoffs years) happened exactly as the league was not very good (while he was playing on the very good team). There are good reasons not to take the 44 pts in 29 games figure a face value. (For the record, Lach suffered an injury in 1947, missed the playoffs entirely, and the Habs bowed out in the SCF to the Leafs. In 1948, the Habs would miss the playoffs, despite Lach winning the Art Ross; if I got things right, that's the year where only 3 players scored 10 goals or more.... one of them being a D-Man. And in 1949, Lach suffered an injury and played very little playoff hockey.
(I'll have to link to this post whenever Lach's up for voting)
The point of this post is : Maybe Elmer Lach is a better player than Joe Thornton. Maybe he's not. But if you think he is, and your main argument is "Playoffs ZOMG", you probably should seriously give it another go. And if you still think he is, well, give it ANOTHER go. I don't see Lach and Thornton having any kind of huge advantage one over the other.
And that's coming from what was probably Thornton's biggest detractor in the Centers project.
