When pushed about this statement and comparing the level of talent to the level of talent the team fielded in 2010, Rex said that it was less about that and more about the atmosphere and camaraderie. That it was more about the dynamic, the leadership, the exuberance and the communication.
While Rex granted that there are still mistakes being made by the team (running backs dropped two handoffs today) he loves the way "they are pushing each other" and spoke at length about how he feels this team is great at communicating to each other.
It's an interesting point. With a raft of young players and a few veterans, the hierarchy is very apparent. Dawan Landry is the "old man" in the secondary. So is Kyle Wilson. Some of the spectres that players like Santonio, Sanchez and others might have had with the team aren't here anymore but Rex likes the new dynamics developing.
