it's not touching my body/leg most of the time... even if it touches, it will rotate like a wheel.....
I ain't no expert but I did my fair share of studying and doing deads. I think the bar should remain as close as possible to your body the whole time...
Don't think you should over extend at the end of the movement. Your back seems okay before you start but that changed when you starts the movement. Your hips shoot up too fast...keep your core tight, chest up... head look forward
I'm no expert, but the negative part of the movement can be faster... drop the weight faster but don't just let go la...
