There was once a mid-sized law firm that wanted to develop a specialty in a niche area of litigation.
At the bottom level of that specialty, there were general commercial litigation lawyers who wrongly thought that they knew enough to be competent. One step above, there were lawyers with a decent reputation who gave good, creative, advice and achieved decent results most of the time. And then there were the Tier One superstars. Big reputations, high billings, and in demand for the most difficult assignments.
