What's up with the Diaz vs Lawlet size difference?

[elcj]

Diaz looks waaaaay bigger, a whole weight class at least.
Does Lawler muscle really weigh that much? What am I missing?

You can see Lawler doesn't have the power due to size/weight difference though

Why do you think they changed the fight weight numbnuts? Stupid thread, watch the fight.
