I would guess that at least 1/3 of the tackles in any NFL game would be illegal in rugby. And I'm not just talking about tackles where the tackler leads with their head. It's just a fundamentally different game.
Nevertheless, concussions and CTE are a significant problem in rugby as well.
I don't think the answer is going sans helmets, In fact, that would lead to more concussions from the head violently hitting the ground (a big issue in rugby). Now, I'm not suggesting that there would be more concussions without helmets. Rather, I don't think going helmetless would eliminate concussions.
I think a better route would be to develop better technology to monitor head impacts, and to use things like helmet sensors to determine when a player should be pulled from a game and/or sat for the rest of the season. In many instances doctors suspect that it is the repeated small blows to the head, none of which are individually severe enough to concuss, that has led to long-term brain injuries for football players. If we had a reliable way to monitor cumulative impact it would be a potentially life-saving measure--or life-prolonging, I suppose. It would also lead to players being more cautious in how they use their heads, knowing that if they repeatedly put their heads in danger their season (if not career) might end early.
You could even use the same system to penalize players who illegally cause head impacts above a certain threshold. Instead of a $50,000 fine for that helmet-to-helmet hit on the quarterback, a player is out for X weeks, without pay, with the number of games dependent on the measured severity of the hit.
Helmetless football, in my opinion, would not be football--especially at the collegiate and NFL levels. On the other hand, I think it should be done in youth football.
