Counting the fatalities from football

There is an Annual Survey of Football Injury Research produced by the NCAA and related organizations. It goes into a fair amount of detail. One classification is fatalities those that happened when playing football covering the period 1931 - 2013:

Sandlot         180

Semi-Pro        80

High School   686

College           89

Total           1035

Those that were related to football, such as heat stroke, in the same period:

Sandlot         115

Semi-Pro        23 

High School   502 

College         119 

Total             759

That works out to almost 22 deaths per year!
