I did a deeper dive because I was really surprised by Forsberg's numbers. As expected though,
@pnep is right - Forsberg played in 41 elimination games during his career and only had 29 points (12 goals, 17 assists).
He had 21 points in 20 wins, and just 8 points in 21 losses. Or looking at it another way - Colorado went 5-14 when Forsberg was scoreless in elimination games, 10-6 when he had one point, and 5-1 when he scored two or three points.
This wasn't "skewed" by his post-lockout peak (28 pts in 38 games before the 2005 lockout, 1 pt in 3 games after).
He had some huge games of course (the biggest moment was probably in 2002, when he scored the final two goals of the series against San Jose to help the Avalanche come back from a 3-2 series deficit) - but there were way more scoreless games than I remember (including one stretch with three assists in nine consecutive elimination games - actually ten consecutive elimination games, one of which he missed). That's not to place all the blame on Forsberg of course (they ran into some very good goalies including Joseph in 1998, Belfour in 1999, and Nabokov in 2004, and Sakic had his share of scoreless elimination games, but appeared to be more consistent).
One more point - of the 38 elimination games he played in before the lockout, Colorado had the series lead 22 times, their opponents only 8 times, and there were 8 game sevens. You can probably argue that, if not for Forsberg's scoring heroics in all of the other games, Colorado wouldn't have been in such a favourable position so often.
