Most NFL fans love statistics and here are some fairly shocking stats based on allocating players and head coaches to their individual 12 birth year related symbols of the Chinese Zodiac.
For example, all those 68 NFL head coaches, who were born in the years of the Pig, Monkey, Tiger and Horse have only won one single Super Bowl in 50 years.
Over the same period the two leading sign groups of the Goat and Dragon have won 20 Super Bowls at 29 appearances.
And in 2016 we saw the very first Super Bowl in history with two head coaches clashing, that were born under the same Chinese symbol, what has given the Oxen 2 more names on their success charts with now 6 wins at 12 appearances moving them on to 4rth place.

So, if you were a team owner, from which sign group would you want to hire :-)
And now the 49ers had to learn another quick lesson after having replaced a head coach from the winning "Rabbit" group with Jim Tomsula from the never winning "Monkey" group.
In fact, with Chip Kelly they have gone straight back to "Rabbit coaching" like it was under Jim Harbaugh and George Seifert.
The currently perhaps most recognized head coach in the NFL seems to be Bill Belichik from the Dragon sign group, which ranks on 2 with nine Super Bowl wins thanks to Mike Shanahan and Joe Gibbs.
But also the NFL Europe has been pretty much dominated by three impressive "Dragon head coaches" with Peter Vaas, Dick Curl and Galen Hall, who have won some astonishing five World Bowls in a row from 1998 until 2002.
With Berlin Thunder Peter Vaas has reached three World Bowls, from which two were won from an underdog position.
Also Rhein Fire's Galen Hall has reached three World Bowls, from which two were won at the stadium of rival Frankfurt Galaxy.
Dick Curl has won World Bowl 99 with the Frankfurt Galaxy against the powerful Barcelona Dragons.
Mike Jones did win his first two World Bowls as receiver coach under "Dragon" Galen Hall. And later with Frankfurt Galaxy he won World Bowl 2006 before he lost the final in 2007 against the Hamburg Seas Devils.
Doug Graber could win the World Bowl one time with Frankfurt Galaxy in 2003.
Bart Andrus has won World Bowl 2005 with his Amsterdam Admirals.
Jack Bicknell has won World Bowl 1997 with his Barcelona Dragons.
Six of the 19 Super Bowl winning NFL teams have hired head coaches, that were born in a year of the Rabbit and 12 from all 32 positions are filled by Dogs & Rabbits.
Monkey Jim Tomsula had been the top loser of the past season and now it could be Doug Pederson at the Eagles, who might continue their almost unique 50 years of Super Bowl failure.
Unfortunate Bruce Arians and Bill Belichik have fumbled over two Ox year born colleagues to miss Super Bowl 50 while this season might be better for them, at least until the final playoff games.
Championships were won by Troy Aikman and once again there are 4 Horse year born head coaches in the race who will once again be having a hard time to reach the playoffs with the Cowboys, Dolphins, Jags and Lions.
Super Bowl 50 wasn't in reach for Chuck Pagano, Mike McCoy and Mike Tomlin and it also seems doubtful, that they will play a significant role in the 2017 playoffs.
Panthers' Ron Rivera is lucky to have "top Snake" Cam Newton on the field while Broncos' Gary Kubiak was riding his "Dragon" Peyton so well. So let's see if they will be gunning once again for Super Bowl.
Leaders in Super Bowl wins remain the Goats with 11 titles scored by not only by Bill Walsh, Jimmy Johnson and Chuck Noll while Jay Gruden and and John Fox will have to intensify the positive trend of the past season.
Buccaneers former head coach Lovie Smith was replaced by Dirk Koetter and in the race are now 6 Dog year born head coaches.
Baltimore Ravens' John Harbaugh and Bills Rex Ryan are the 2 Tigers in the race for Super Bowl 51 and their chances seem to be once again very slim.
Houston Texans Bill O'Brien will be once again the only Rooster on head coach and certainly his chances for reaching Super Bowl are not that great though it will take place on February 5 in the year of the Fire Rooster.
