where you look is almost irrelevant. Look up some of the top deadlifters in the world and you'll see every which angle of their head. They aren't all the same. The spine is NEVER "perfectly straight". A certain amount of flexion happens even when you don't visually see it. A lot of advanced lifters have a slightly rounded back. In fact, it gives more room for spinal extension to occur. As for "down in a controlled motion" - 1) he was literally demonstrating fast eccentrics to demonstrate what NOT to do 2) when he did show it properly, it WAS controlled. I don't know what on earth you were looking at. As far as the bar sliding on the shins...look a speed deadlift is with 30-40% of your max. It's not going to be locked in as much as a maximal lift.

he's actually pretty fukin strong
