If that is correct (and I assume you are), then Lester Patrick was the first to use 2 lines. He did that in the 1925 Stanley Cup challenge. Apparently, he knew his guys couldn't keep up to Morenz and Joliat all game, so he employed a two lines so they would always be fresh, and they'd be able to give more effort.
We'll give Odie credit for being the first guy smart enough to copy Patrick!
Quite possible that Patrick used it as a specific strategy to contain Morenz and Joliat during the 1925 Cup finals, and Cleghorn saw the success and then became the first one to use it as a full time season long strategy
