I am curious as how the rate of inflation of the USD compares to the salary of say, a linebacker for the Green Bay Packers for the years 1966 and 2016. I found an online calculator to estimate the rate of inflation for the dollar: $1 in 1966 compares to $7.53368 in 2016. It gave me: Average inflation rate of 4.12144% and a total inflation rate of 653.36835%. But I can't find 1) salaries for comparable linebackers of each era and 2) an online calculator to figure it out for me. 
I did not choose quarterbacks because without even doing the math, I'm sure the "inflation" is through the roof and off into space past the second galaxy on the right.
If nothing else, the above is a problem JAPF can offer his students. 
(I always hated that famous: "If train A leaves the station at 5:05 a.m. going 30 mph and train B leaves the station at the other end of the line at 6:15 a.m. going 25 mph and the track is 50 miles long, when will they meet*?" (*AKA, mass destruction and loss of life.)
