The more interesting, and perhaps surprising, comparison is to 1977. The most significant set of rule changes favoring the passing game came in 1978: the 5 yard chuck rule, offensive linemen allowed to use their hands, and QB protections.
In 1977, the pass/run play split was 17/37 = 64 vs. the gradual rise in passing to 35/28 = 63 in 1995 where it has remained relatively stable since other than a slight tick down in rushing plays, two fewer since 1995.
There are other plays not counted in these stats. Penalties, +1 since 1977. There are also sacks, not recorded as an official stat until 1982. It would stand to reason that throwing twice as much since 1977 would lead to more sacks not recorded in the pass attempts.
Still, where did all the clock time go in a pass happy league with incompletions stopping the clock?
One factor is KO and punt returns. Back in the day, those kicks were routinely returned, burning incremental clock. Now, its an series of touchbacks and fair catches.
It's also worth considering that back in the day when teams ran the ball 37 times there were a fair number of what were called "sweeps" where the runner would be tackled out of bounds. Today, the "outside zone" as it is called in Green Bay today, a variation of which McCarthy also ran, has become increasingly popular, the concept being to get defender momentum to the outside opening up inside cutback lanes. You don't see many runs today where the ball carrier turns the corner and gets tackled out of bounds.
Another factor is the frequency of play stopage for a measurement. With all that short yardage running back in the day, you might see a couple of those per game. Now, they're uncommon. Has there even been one in the Packers first three games this season?
Perhaps the more perplexing factor in comparing 1977 to current conditions is the play clock was 30 seconds back in the day. However, back in the day you wouldn't see no-huddle or hurry-up offenses outside the 2 minute drill. Now you could see it any point in a game which would account for some offset to the longer play clock. The Wyche/Esiason offense in the late 80's, and then the Kelly K-Gun in the early 90's where Buffalo would run hurry-up for an entire game, initiated the concept of hurry up outside the end of halfs.
I'm sure there are a lot of other factors I'm not thinking of.
