Here's an important excerpt from my book on deadlifting, Off The Floor, on weak links. TL;DR: it doesn't do you any good to have stronger hips if your spine can't transfer the force.
"What is the biggest limiting factor in the deadlift? By now, you should know that the answer is always “it depends.”
If you said hip-extension strength, you’ve given the most popular answer, but I think it may be overstated
During a deadlift, your shoulders, hips, and knees form a triangle. The length between hips and knees is completely fixed. The length between hips and shoulders can vary based on the degree of curvature of the spine. Certainly, in a comically light deadlift with perfect form, the spine is perfectly neutral and remains a fixed length. However, in a heavy deadlift the spine is very often in a semi-flexed (or rounded) position, at the very least in the upper back. In fact, some of the best deadlifters (Konstantinovs is a notable example) will start out in a rounded upper-back position.
This curvature of the spine and shortening of the length between hips and shoulders creates a problem. The length between knees and shoulders is always going to be the same at lockout. If the spine is flexed and shortened, the hips cannot close the gap to the bar without forcing more curvature into the spine — assuming the upper back is the weak link. The geometry of this triangle must remain constant. This is why you see deadlifters fail just above the knee, when it seems like all they have left to do is slam their hips into the bar. The harder they try to extend their hips, the more they are literally fighting against their own spinal extension strength."
