“I do think Josh can have an impact on this game this weekend. Not in terms of his knowledge of Tim Tebow, but more in terms of his knowledge of Denver’s defensive players, and the players in general,” said Mangini, who is currently working as an analyst for ESPN. “Because as a coach, your whole job is to help players improve on their weaknesses. And to try to get them to play better based on trends, but more importantly to take care of those weaknesses. “In this situation, Josh can sit down with Tom (Brady) and say, ‘OK, these are the issues the guys in the secondary have. These are the issues the linebackers or defensive linemen have.’ That’s where I think his biggest impact is going to be.”
