HOUSTON – An adage in the legal profession is that a lawyer who represents himself has a fool for a client.

Sadly, Houston Texans wide receiver Andre Johnson(notes) is learning the NFL version of that saying the hard way. Even after he recently hired agent Kennard McGuire to represent him, the lesson will likely cost him around $20 million over the course of his career.

Until hiring McGuire, Johnson essentially represented himself, using uncle Andre Melton as an advisor. The result of that decision has been a costly mistake for a player who is perfect in so many other ways. Aside from being a great player, Johnson is extremely classy and is roundly praised as a helpful and generous teammate.
