By the way, in almost 100% of cases (the rest being just OA or something legally really dubious), the authors have a right to send their paper, even if it is published in the journal. Basically, the only thing the journal has a right to for subscription-based (aka those that cost $35) articles is content plus page layout. If the authors have the exact same text but formatted differently, they are free to distribute it wherever and however they want.

Preprint servers or lab/personal websites are best first choices for that.
