Lighter PLers lift heavy, but don't take in the huge number of calories (protien or carb) that the big boys do. They get stronger, but they don't get more massive. That alone proves that strength doesn't necessarily = size.
Now, there may be a practical limit that they can reach without the huge intake, but, for everyone but the elite of the elite of their class, they can still gain strength without having to move up weight classes.
The real question is, "Can you get size without proper nutrition?"
It probably turns out that, like so many things in life, the answer is "Maybe".
Some people have metabolisms that make better use of what they eat, so they don't have to cram themselves full every other hour to gain size.
Some people have metabolisms that aren't so efficient, so they're forced to take in a larger number of calories to compensate.
That's what makes BBing and PLing part art, part science.
