I care about the concussion issue a lot, and I think they need to continue to research and develop ways to help with that (if there are ways). Things like horseshoe collars and chop blocks and so on, as well, where guys can get injured by unprofessional behavior.
I do not, however, care for or about the way the quarterback position is treated. They might as well just put a 3 foot halo around them and be done with it. And that has nothing at all to do with player safety, that has to do with owner security, and the risk of losing hundreds of millions if their guy goes down. And I do mean hundreds, it involves a lot more money than just the contract.
