"Mularkey said Shaw's release wasn't meant to send a message to the team. Rather, the coaching staff felt they could improve the production level with his roster spot.
"When I say production, it is game, practice, meetings, and anything affiliated with what you do with your job," said Mularkey."
I heard a similar comment from Mularkey about McGahee - saying that this past week he improved his production in those situations prior to the Jets game. Perhaps that is another reason why McGahee wasn't getting the game time the last few games before the Jets game.
This gives me a glimmer of optimisim for the rest of the season. Working hard during the week will lead to working hard during the game.
