There is something to that for sure. If you look at the leather helmet days, or even at Rugby today its more of a tackling game than a collision game that the NFL is today.

The concussion rate was about 18 times higher than average for rugby, five times greater for hockey, and roughly double for American football, the study found.
For each of the sports, they looked at concussion rates based on minutes of athletic exposure (AE), which includes competitions or practices with the potential for injury.
The overall concussion risk across all of the sports included in the analysis was 0.23 injuries per 1,000 AEs.
By comparison, the concussion risk per 1,000 AEs for rugby was 4.18, while it was 1.2 for hockey and 0.53 for American football.

The NFL, which has a lower rate of concussion than in rugby, is close to finalising a settlement worth $1 billion (£655 million) to more than 4,500 players for hiding the dangers of concussion-related head trauma.
