My opinion is that the one who has the strongest clean has the strongest deadlift.
People misconceive that the Olympic lifts are NOT strength exercises. They are. And the reason why they end up NOT becoming strength exercises is because 99% of the population can't do them properly.
They don't overload your raw strength like squats and deadlifts do. And that is because they are complex.
A weightlifter must be strong, fast, and well-coordinated.
A random guy in the gym who wants to get stronger just needs to get stronger. That's it. And yet these random gym guys can't get strong even though it is the only task they have! Weightlifters must be doing something right.
