players by how players perform, then Ziggy is Exhibit A. He knew exactly ZERO about football and Bronco taught him to be a superstar (i.e., Bronco taught him to play to his potential).
The double standard really lies with people saying that Ziggy was good because he was talented and it had nothing to do with coaching. Well, what about when players are bad? Why isn't that 100% based on their talent like it was with Ziggy?
