You would have to have the full context of the conversation to be able to accurately speculate about his motivations to play or not to play. But, just from what I see here, he alluded to the fact that he has been playing well, before he said anything about "bad film." If he only meant that he wouldn't want to play if he would look bad on post-game film to the coaches and the other players, there would be no need to reference his past performance. I think he is clearly concerned about his overall body of work this season, as it appears on film, and that is almost certainly concerning a new contract.
Now, with that said, these players have mixed loyalties. They do care about winning, and they do care about the team and their teammates. They also know that their careers are short and often physically, and sometimes mentally, debilitating. If they don't make decisions now about their future financial situation, and if they put the team before their families, their loyalties are in the wrong order. We, as fans, can afford to support the team 100%, and it is easy for us to say, "take one for the team." Players cannot afford to do that. If Hatcher wants to sit because his play would not appear to be big-contract-worthy, I have no problem with it. Especially knowing that when he does come back in, he will be giving all he's got to make a splash on film.
On the other hand, it also tells me that once he gets his big contract, his incentive to make a splash will be significantly diminished.
