Found this blurb on Norv Turner...
"Norv Turner learned the offense from longtime Coryell assistant,
Ernie Zampese. As offensive coordinator with the
Dallas Cowboys, Turner ran Coryell's offense a greater emphasis on sideline throws than the Chargers used.[SUP]
[20][/SUP] Turner's take on the Coryell system turned around the career of Hall of Fame QB Troy Aikman and has proven to be very successful with talented high draft picks struggling with the complexities of the NFL, such as
Alex Smith. Turner' variant is not the most robust flavor of Coryell offense. It is a very sound, QB friendly scheme that favors taking controlled chances, like quicker midrange post passes to WRs off play action rather than slower developing passes that leave QBs exposed. It is almost exclusively run out of the pro set. Turner favors a more limited palette of plays than Coryell and most other Coryell disciples, instead insisting on precise execution. His offenses are usually towards the top of the league standings, but are often labeled predictable. His offenses tend to include a strong running game, a #1 WR who can stretch the field and catch jump balls in the end-zone, a good receiving TE to attack the space the WRs create in the middle of the field and a FB who fills the role of a lead blocker and a final option as an outlet receiver. In Dallas, Turner made RB Emmitt Smith & WR
Michael Irvin Hall of Famers, and TE
Jay Novacek a five time pro bowler. As head coach of the San Diego Chargers, Turner's system helped quarterback Philip Rivers set new franchise records for single-season quarterback rating and touchdown passes in 2008."
