I honestly feel the exact opposite with character issue players. If you have a good leadership group, you should bring them into the fold ASAP. Ryan Getzlaf is a very prime example of just that. Big character red flags caused him to drop. They got him up right after the lockout around some of the best leaders in the game and he matured very quickly. Keeping these kids away from real structure, leadership, and teachings on what it means to be a pro does them a larger disservice. If you have a good leadership group, you bring players like this in early. The sooner they are around good pros, the better.
