I believe the poster was questioning whether "I'm not being developed" is an excuse for not putting in the work needed to develop.
Shammond Williams "developed" by shooting jumpers at the gym until midnight. While the coaching staff and the court opportunities play a role, if the player isn't going to put in the work off the court, it's not going to work.
Vince Carter, for instance, might have transferred after his freshman year in today's world. He wasn't getting enough opportunity, he might say. What actually needed to happen was for him to work harder on his shot, handle and defense. And to his credit, he did all that -- probably putting in extra hours all year long. Had he transferred, I suspect he would not have worked as hard; he would have found an easier way to get the PT he wanted. Like Cliff Rozier.
So, sure, transferring when development is blocked is not a problem. Using that as an excuse for not working benefits nobody.
