The science doesn't agree with you guys. On an individual scale, sure, a deformed, learning disabled fish could by chance make it through to trophy size. But from a fisheries management standpoint, across the thousands of fish making up a lake's population, the vast majority of big fish will share certain characteristics. Growing fast has a lot of advantages in the fish world (ability to consume larger prey, move faster to escape predators, carry more eggs); the biggest force selecting against big fish is man. Big fish don't get big by chance alone, any more than big people get big by chance. Just off the top of my head, Texas's "Share a Lunker" program is a good example of a management program that is trying to improve the genetic stock of a set of lakes to produce bigger fish.
