Here are the answers:

George Halas  497  Don Shula  490  Tom Landry  418    (Bill B. has  384 under his belt.

2. Name those  5 Head Coaches...who have coached since WWII....who have the 5 highest Win Loss percentages in their NFL coaching careers.   Hints: A. None are the same as the names in Q#1.....and B....there may be a surprise or 2 in there.

4. In the History of the NFL, only  7 HCs have won  200 games.  Three of them coached the Browns and  one played his career for the Browns.  Name them.

Paul Brown,  Marty Schottenheimer and Bill Belichick  coached the Browns.   Don Shula played for the Browns.  The only three that had no Browns associations have been George Halas, Curly Lambeau,  and Tom Landry.  IF you include those who have 200 wins....including postseason, that bring the number up to  10  HCs with that number,  with Chuck Noll and Andy Reid and Dan Reeves included.  Chuck Noll of course played for the Browns...and is a native of Cleveland.

5. Two teams have won Championships in their history under  4 different Head coaches.    Name these two teams.

Packers with Lambeau, Lombardi, Holmgren and McCarthy

Giants with Steve Owens, Jim Lee Howell, Bill Parcells, Tom Coughlin

6. In NFL history,  which state has had the most different stadiums play host to NFL games?

8.  What is the only stadium that was used in the inaugural 1920 NFL season....that is still being used today by a major league sports franchise?

Wrigley Field was used by the Chicago Cardinals in the 1920 season.  Of course, it is still used by the Cubs.

9. A.  Which Stadium  hosted the most NFL games in history?    Hint:  now defunct

"Giants stadium"   The Meadowlands in New Jersey.  492 games. The key of course is that from like 1974 to 2011 or so.....that stadium was home to 2 NFL teams...so it really got twice as much use as any other stadium.

B. If you can....name the other stadiums in the Top 5 in this category.

#2  is Soldier Field  420 games    #3 The LA Coliseum...402 games and counting  #4 is Jack Murphy/Qualcomm  Stadium, San Diego. 398 games.  #5 is Cleveland Municipal Stadium.  Used by the Browns, the Rams and at least one other NFL team.

While the LA Coliseum is scheduled to be used only temporarily....the next two on the list are  Lambeau Field,  375 and Arrowhead Stadium 374....those two will be carrying on for some time yet, clearly.
