As Andy mentioned, this is far from the first time a player has been considered 'inactive' until he passes the conditioning test. The only difference is, this one has been made very public, as Haynesworth's contract has been controversial from day one.
The fact remains, any player - regardless of how much they are being paid - that is not suffering or coming off from an injury, should come to camp in shape and ready to pass the test. From what I've been hearing, the test should be simple for all professionals.
This is a humbling moment. A chance for Haynesworth to swallow his pride and realize he is not bigger than the team he plays for. He is another piece of the puzzle that must work within the team's culture for the team as a whole to be successful.
That said, Haynesworth was never in great shape, ever. If you watch his Pro Bowl seasons, the majority of his dominating plays took place in the beginning of games, when he was fresher and had his legs under him. He is a player that needs to be managed....sitting out many plays to go in and make one statement.
