Depends what kind of player he is.
A 30 goal scorer who's a sniper who hangs out at the circle, doesn't forecheck or go into corners, and is late getting back b/c he's looking for a breakway instead of taking care of his defensive responsibilities doesn't have a lot of value. Especially if he's getting half those goals on the PP where he can be replaced fairly easily (much harder to find ES scorers).
I'd rather have a 20 goal/50 point guy who sets up teammates, forechecks, does the dirty work, cycles out of the O-zone properly, gets back on defense, and can play on the PK.
