The fans are calling for his head, for his job, for a change in the leadership of the San Diego Chargers. Him being head coach Norv Turner.

You judge a coach not by how he dresses. Not by how loud he is, not by his smile or scowl. You judge him on wins and losses, success and failures with players, and what they have done in postseason.

NFL coaches come in all sizes and shapes, with all types of personality traits, quirks and styles. There was the jaw of Bill Cowher in Pittsburgh, the stoicism of Tony Dungy in Indianapolis, the bluster of Rex Ryan of the Jets, the solemness of Bill Belichick and the sales pitch of Marty Schottenheimer.

And then there is Norv Turner. Not very demonstrative on the sidelines, never smiling during game situations; more like a choir boy, than a hell raiser with a headset. This is the best coaching job he's ever had, with the finest quarterback he's ever had, and it appears it may end as badly as it did for him in Washington and Oakland. Once upon a time, it was a ticket to the playoffs. This time it's a pink slip.

Who is Norv Turner, and why is he so disliked? Why has a dream job become a nightmare? Should we have seen this coming? Was this predictable? What will the outcome be?

Ask anyone who has worked with Turner and you get rave reviews, from longtime USC and Rams head coach John Robinson to Dallas Cowboys icon Jimmy Johnson. The 1980s, and his initial success with the Dallas Cowboys was a long time ago. Johnson gave him playmakers, Norv molded Troy Aikman, Emmett Smith and Michael Irvin into a Super Bowl machine.

The Cowboys success led to a head job with the Redskins, where he struggled with talent, had good seasons, then bad seasons, and was fired. He rebuilt is reputation again as a coordinator, and spent a couple years with the Raiders, where he dealt with the same situation. A less than stellar roster, marginal statistical success, then an ouster.

His arrival in San Diego was met with criticism from the first day, for he inherited a great roster from a popular coach, Marty Schottenheimer, unceremoniously dumped by GM AJ Smith. It was hard to replace that coach, but he won early. Now the same storylines that took him down with the Redskins and the Raiders, have resurfaced here in America's Finest City.

It's interesting to look at the stats Norv Turner's teams have put up in his three head coaching jobs. It's also interesting to see how much he got out of the quarterbacks worked with. But it is equally alarming to recognize the same traits in San Diego, he experienced in Washington and Oakland.

The Chargers quarterback Philip Rivers blossomed under his leadership. In a four year window leading into this season, Rivers threw 113 touchdowns. You don't throw for 4,700-4,854 yards in back-to-back seasons unless you are good, the talent is better, and the play calling is excellent. It brought back memories of Dan Fouts/Air Coryell, and this Rivers/Turner combo was magic, but now, not any longer.

The stats put up by Turner's quarterbacks in Washington and Oakland were impressive, but their names were not impressive. What he did with Brad Johnson, Jeff George, John Friesz, Trent Green, Jeff Hostettler and Gus Frerotte is absolutely amazing. He took street people and in a given season, made them NFL passing stars.

Johnson, the bounce-around journeyman, threw for 4,005 yards one season. Green came off the scrap pile and threw for 3,400-yards another year. Frerotte threw for over 6,000 yards combined in two seasons. In Oakland, at the end of his career, Kerry Collins threw for 3,495 and 3,759 yards in the two years they were together.

Those are amazing individual accomplishments, added to the fact Turner had to answer to meddling owners Dan Snyder and Al Davis. The end results of his three tenures as a head coach are simple. They will throw the ball, put up great stats and may win some games.

The quarterback numbers are in the spotlight, but in the shadows one must consider the dark side of his head coaching career. Heading to this weekends game in Jacksonville, Turner's head coaching record is (108-115-1), much of the positive numbers an off shoot of time with the Chargers.

But his numbers are skewed by the fact his teams are streaky. In San Diego, he's had an 11 game and an 8 game winning streak, but has also seen his team dive into a 6 game tailspin. It was much the same with the Redskins and Raiders. He had 5 and 6 game losing skids in Oakland. In Washington, he had a 7 game win streak, but also seasons of where they lost 4, 4, 5, 7 and 7 games in a row in different seasons. For every good stretch, there was a skid he could never get his team out of.

And despite the heroics of his quarterbacks, Turner's teams always managed to come up short. Of the 115 losses in his career, 67 were by a touchdown or less. With all that firepower he created, they just never really won with any consistency, coming home losers more than winners.

Off the field? Turner is a great family man, who came from a very tough dirt-poor background in Northern California. A man who donates time and resources to charities I'm also involved in, feeding the homeless and assisting the Multiple Sclerosis Society.

At the end of the day, however, Norv Turner will be known for a couple of things. Good enough to develop quarterbacks and run up statistics, but not good enough to win consistently. Good enough to get you close, but also to get you beat in close games.

He was a back-up quarterback at the University of Oregon to the legendary Dan Fouts. His NFL career will likely finish up with "A Great Offensive Mind" on his tombstone.

To quote his GM AJ Smith, who put him in this job and has failed to give him enough quality players, "It is what it is." Sadly, for Norv Turner, it's probably the end of his head coaching career. Remember that old phrase, that the NFL stands for "Not for Long" if you don't win?

Norv Turner is a quality person, but nothing more than a career offensive coordinator. A good man, just not a good head coach.
