The '60s were a lot different than the '70s, and in many ways, the '50s were more like the '00s. I think using "pre-1978" as a proxy for "1971 to 1975" is something to avoid. In my opinion, you'll be hard pressed to find a more unusual five-year period over the last 60 years than the period from 1971 to 1975. That, to me, is the big outlier in pro football history. The passing game plummeted in the early '70s, which is what led to the rule changes and the steady increases in passing production we have seen since then. But it's important not to confuse the early '70s with the 20 year period (even ignoring the AFL) from 1950 to 1969.Chase Stuarthttp://www.pro-football-reference.comnoreply@blogger.comtag:blogger.com,1999:blog-5204092591876211047.post-89675479162471098322011-10-06T13:59:13.922-04:002011-10-06T13:59:13.922-04:00I don't think it ever would have occurred to m...I don't think it ever would have occurred to me that the relative importance of Y/C and C% would change over time.
