Not every player has a guy sitting behind him who is potentially better. Justin Smith got hurt, no one came off the bench and took his job. If Dashon Goldson gets hurt, I doubt CJ Spillman or Trenton Robinson is going to step onto that field while Dashon is recovering and take his job. BUT--if you have that much depth, THAT'S A GOOD THING FOR YOUR TEAM. The better player should always be on the field, right? If you're a team player you should be happy that the team is being given the best chance to win...not that it wouldn't be a tough pill to swallow.
A player that lies about injury and plays anyway risks not just the team's well-being (by playing poorly) but his own. Suppose Alex plays through the concussion, gets hit again and has another, more severe concussion? He's negatively impacted his career, his future marketability, and his long-term health. Bottom line, players still have the responsibility to be smart about themselves and their careers, so I don't buy this "players will be motivated to lie" (any more than already exists in macho NFL culture).
Then you doubt self preservation. These players will justify it by saying they're not really hurting the team and that they're not really risking themselves. In Alex's example, he possibly could have played through it if he had denied it, the new rules were what kept him out of the game. Guys play hurt all the time, this is no different.
