I've seen a lot of guys get hurt with these that don't pull from the floor and haven't adequately built up their posterior chain.
Also, dead lifting is very taxing on your CNS and when you miss one, it is very defeating to your ego. Too often, guys do partials to throw around big weight, use them if you need them, work them in as a ME movement but don't get sucked in by the appearance of being that strong, give it time, it will come regardless.
You'll think me in the end and that's my 0.02... for what it's worth.
