Query: A Few Detailed Facts Are Wrong!

The book is a good reference but not as accurate as the Internet or Google today. For example, the book has the wrong information on what College actually put numbers on Football Jerseys. According to the History of American Football and Sports Illustrated in 1908, Karl Davis, at the time publicity man for the University of Pittsburgh, first put numbers on college football jerseys.Davis used that good old sales pitch, "One cannot tell the players without a program!" He quickly added to this service the refinement of switching the numbers each week due to Davis having the program concession. Davis thus became a double pioneer in player numbering and in "dynamic obsolescence". Both inventions have come a long way since.When I see such errors, I wonder how many other facts the author got it wrong or just did sloppy research. Anyway, the Internet Age has made such books obsolete and mistakes unimportant since they can be corrected easily today with easy research.
