Josh leads by example on the field. I don't recall ever seeing him get on another player that is not playing up to the level that is expected. Somebody needs to hold players accountable on the field and get their head in the game when needed. Is that the role of the QB or the coach? It doesn't seem to be Josh's nature to act like "Tom Brady".
Some guys play like they are having fun. Some guys play like it is life or death. They don't always agree.
