OK, I know the entire premise of BTTF is goofy, physics-wise. I won't get into the time travel logic. What I DO want to mention, though is that, for being an almanac showing 50 years of sports scores, that book is ***AWFULLY SMALL***. Here's my reasoning:
I assume that all regular season and post-season scores would be shown for professional sports such as Major League Baseball, National Football League, National Basketball Association, and National Hockey League. In addition, all College Division I games would be listed as well. Finally, from the
Grays Sports Almanac cover page, boxing and horse racing is included.
That would mean that a book that looks about the size of a large Dell Crossword magazine, about 150 pages at 8.5 x 11 inches, would contain the scores of over 160,000 baseball games, 44,000 NFL Games, 87,000 NBA games, and 76,000 hockey games, professional level. In addition, as mentioned in the movie, colleges are included, so I estimated a very conservative 75 Division I colleges who play 12 games apiece per year, not including bowl games, for another 45,000 games. If you throw college basketball in the mix, include at LEAST 90,000 games, including playoffs and tournament games. By the way, although the calculations are rough, they ARE very conservative as I used the amount of teams in 1950, 1960, 1970, 1980, 1990, and 2000, as well as the length of seasons, to create my calculations.
Without boxing and hockey, we are looking at an almanac that lists over a conservatively estimated HALF A MILLION sporting events. With formatting and the smallest print for such an almanac, the book would have to be at LEAST 5,000 pages long, not the 150 shown.
