Jefferson Curl Strength vs Deadlift Strength

I think it's pretty clear that for most meathead lifters who are proficient in squats and deadlifts have very stiff spines and will not be able to correctly jefferson curl hence they are very strong with a neutral spine but completely inept in flexion. 

In regards to the inverse: Is an athlete who can lift hefty poundages in the jefferson curl going to also be strong in a normal neutral-spine deadlift?

Well, keep in mind that the training is always specific, if you want to maximize performance with a straight spine then your training should be focused more on that BUT since strength training is cyclic there is a point where you must dedicate some time to strengthening the weak point, like the spine.

The strength training at some weight or effort creates a general amount of fatigue that can be increased with additional JC work. this means that choices should be made.

For a novice, a good JC gives a general better physical preparation but this doe not mean that he is going to develop higher weight simply because technique, programming , volume, intensity are the biggest part of the game.
