Yes.
There has always been a discussion, for example, that there should be no head contact. There are other leagues at a lower level that have such a rule, which is inconsistently enforced, and there are still head hits.
What we're trying to do at the NHL level is to strike a balance, which we do with the players. This is something that the players feel strongly about, that we strike a balance to maintain the physicality of the game and reduce, to the extent possible, head contact. For example—and I'll give you an absurd example—players, as I indicated, are different heights, weights, skills. If you eliminate all head contact, every time a taller player—which most players would be—would check me, there would have to be head contact. If that would result in a penalty every time, there would be no more bodychecking.
