The NFL frequently changes, I'd be happier if the NFL did start changing back to the way it used to be where offenses were more balanced, actually used I formations, and running backs were appreciated not treated like used condoms after a few seasons of usage.
I still believe even in today's NFL a good hard nosed Running team with a good defense can win championship's too.. I'm happy to see teams like the 49ers and Titans succeeding over these stat whoring offenses.. Yeah Mahomes or Jackson might throw for 500 but if the drive ends in a interception or fumble was it really an efficient offense?
