I know it is hard to compare era's but I can't believe the first Super Bowl winning team, the Packers, get no support. That team was loaded with Hall of Fame players and had a time of dominance almost unmatched. Maybe the 66 team was better but this team was pretty good.
Problem is, people want to compare eras and the teams now are so much Bigger and faster than the older eras, so it's really not a fair comparison.
