I agree the owners will not be as quick to make changes when it affects revenue. I think the Thursday product generally sucks and I have heard players complain but not sure it is backed up by injury data, not saying it is or isn't just that I have not seen it if it exists. I think in many cases guys miss a Thursday game where maybe they could go on a Sunday, certainly true for concussions. Also, valid point on the turf, that is a bit tricky for some of the existing domes and whatnot. They should not play on that turf in London at Tottenham and in NY (and probably some other places) so there are things they could do. I will say that long term affects of concussions are probably a different category than other injuries.
