You should rarely be calling down with position. You need to use your position to find out where you are and to charge potential draws and to take free showdowns.

Example: You have QQ on the button and raise one early limper. The big blind, a seemingly sane player, calls. Flop is K T 8 with 2 spades. You bet and are checkraised by the big blind and the limper folds. Calling that and the turn and river is bad. The standard play is to pop him on the turn and usually take the free showdown. He could easily have a hand like AT or a multitude of draws that you need to charge him for and obviously you can release to further aggression. Why else is position so "powerful" as quoted by the pundits?

Calling down out of position is usually fine though.

Basically its just a question of knowing how sane your opponents are. But I pretty much agree that for the most part the "trend" of the LL players on this board put in too much action on the flop and not enough later streets especially heads up.
