Actually it doesn't "destroy" anything because there's two things going on at the same time. The rule changes helped inflate the stats and the rule changes also helped protect the QBs..
We are discussing stats + longevity. The stats are super inflated the past ten years.... that's a fact. The QB's are not getting hit the way they were in Montana's era... that's also a fact.
Both of those facts lead the more passing yards and more passing TDs and LESS injuries. That all helps the current era of QB.
Now go ahead and try to show me where the lie is. THAT's why the 3 of you ran away from the debate.
Yeah the facts are the rule changes of 1978 “inflated” passing stats of 1980’s QBs and protected them compared to their 50’s,60’s and 70’s counterparts
