The only thing explosive is the lifter dropping under the bar. That is what gives the illusion of fast bar speed. And who says you can't pull deads at a fast speed. Also when in sports do you perform an olmpic lift. Football players and wrestlers should not squat olmpic style, if they kept there feet close together they would be easily pushed over. So why train that way?
Sammy, Sammy, "The only thing explosive is the lifter dropping under the bar"? That is totally false. There are two pulls that occur before the dip under the bar, and those are by far the most explosive movement not only of the excercise, but in all of sports. Actually, the second pull (from the thighs) is the more powerful of the two. See my thread about power generation and speed (explosiveness) in this thread for a better understanding:
"Work by Dr John Garhammer, a biomechanist at the Department of Physical Education at California State University reveals some interesting comparisons between exercises in the development of power. Garhammer underlines Starr's remarks that speed for the deadlift is built with Olympic pulls. In "A Review of Power Output Studies of Olympic and Powerlifting: Methodology, Performance, Prediction and Evaluation Test", elite Olympic lifters' and powerlifters' power outputs were as follows (w/kg = watts per kilo of body weight):
During Entire Snatch or Clean Pull Movements:
34.3 w/kg Men
21.8 w/kg Women
Second Pulls:
52.6 w/kg Men
39.2 w/kg Women
Squat and Deadlift:
12 w/kg Men
For female powerlifters, "estimates indicate that the corresponding values
for women are 60-70% as great".
With this basic breakdown in mind, the power output comparisons of a
100-kilo male lifter in the clean, second pull and deadlift would be as follows.
Clean-------------3430 watts
Second Pull----5260 watts
Deadlift----------1200 watts
Obviously, there is a huge difference in power outputs. The power output of clean pulls is 2.85 time greater than a deadlift. Second pulls are even higher with power outputs 4.38 times larger than deadlifts. Garhammer's research showed that even when dropping the training poundage down to lower percentages for Olympic pulls and deadlifts, outputs for Olympic pulls were still almost twice as great. Starr was way ahead of the curve on his training in regards to Olympic pulls for deadlifts. "
