How about this:
Take Eric Lindros. In the years between 94-99, and 2002, he has a 7 year VsX of 85.43. In those seven seasons, he play 81.55% of his scheduled games.
Looking at Hockey Outsider's chart, a 7-year VsX of around 65 makes you a replacement level player in the ATD if you're a modern player who doesn't bring much besides offense. So that means that about a fifth of the time, you're sticking that kind of player in the lineup.
So you take Lindros's entire score of 85.43, because he only needs sixty-something games to put those points on the board, and add 18.45% of the replacement score, which amounts to 11.99 more points. So Lindros's overall offensive impact is that of a player who scores more like 97.42.
Looking at that, it seems like too much, so I'm all ears for someone to tell me why this doesn't make any sense. Perhaps 65 is too high, as it assumes that guys like Simmer, Carter, Paiment, etc, got their scores by being perfectly healthy, and that's not really true. Is there any way to improve this?
