When Edgar Martinez was a bit younger, he had an awesome stance.
Imagine standing on your right leg, then squatting as low as you can. Then, stick your left leg as far out towards the pitcher as it will reach. He then took his bad, held it over his head, and pointed it towards the pitcher (almost julio franco-esque).
Pure awesome.

It kinda shows it, but not quite the low squat from the early 90's.
