I've seen alot of concussions this year that didn't seem to be the result of helmet contact at all. Lewis didn't crash hard into the guy or the ground with his head. Yet, he had a concussion. What the NFL is doing NOW is the right thing for the players. I don't know how it will ultimately be for the league. When everyone's money from top to bottom and the existance of the league itself starts to get threatend, which longterm is possible, I doubt the powers to be will be so noble.
