I appreciate the effort, but this will probably only lead to better acting. If players personally make the call to "be hurt", no coach is going to say they're not. If there's no signal from the bench, there's nothing to enforce.
At some point, there will be descension among teammates doing the same work and being paid a fraction. I think we saw some of this with 8&4 after that #1 class. The locker room will breed contempt.
The crew is a "best of" from all the league officials based on how they graded out over the year. It's considered an honor to be a part of it. The only exception is that none can be residents of Alabama or Georgia.
