For the playoffs, I think I'd rather have Forsberg in his prime than prime Lindros.
Big E played in three playoffs through 1997 and scored 53 points in 43 games in those playoffs, averaging of 1.23 points per game. Lindros was a combined +13 in his first three playoffs.
Forsberg played in 151 games in the playoffs in his career and scored 171 points in those games, averaging 1.13 points per game. Forsberg had a career +54 rating in the playoffs.
That's a difference of just .10 points per game despite the fact the Forsberg played more than three times as many games in the playoffs as Lindros did up to 1997 and despite scoring the fact that the NHL was a higher scoring League in 1995 and 1996 than it has been since 1996 (though the scoring rate was slightly higher in '06 than in '95).
Presumably, Lindros was healthy during those first three playoffs. He certainly was in his prime and not damaged goods during them anyway. Forsberg did have the luxury of having Sakic on his team, but I'd still want him instead for the post season.
