For one, better shows. More fish caught that are allowed to count, the higher the weight. The higher the weight, the more fan interest. The more fan interest, the more money generated. Same thing that the NFL has been doing for years with all the rules on passing and quarterbacks and whatnot.. Also, I'm willing to bet that there are some pros that would push for it. Normally with tournaments there is a five bass limit due to fishery regulations. However, with the immediate release you would not be keeping the fish, therefore allowing the contestants to "weigh in" every fish they catch. And, though I doubt it would happen, it could also do away with length restrictions as a whole. I doubt that they'd do that, but the removal of the limit would not surprise me.
