There is a show on Amazon Prime right now called All or Nothing and it provides a behind-the-scenes look at the 2017 season of the Dallas Cowboys. If you're a football fan and like to see what goes on behind closed doors, it makes for great viewing.

One scene really blew me away. Head coach Jason Garrett walked into a defensive meeting and spoke to the group. Yelled at them, might be a better description. He showed clips from practice and really lit into his players. Not the starters, though. Garrett was upset with the guys on the scout team. Those are the backups who help the starting offense prepare for each game. They act as the opponent in the upcoming game.

The backups were going through the motions. They weren't physical. They weren't hustling. They gave minimal effort, and it sent Garrett into a rage. Those are the players at the bottom of the roster. Effort should never be a question with them. They should go full speed for every rep all season long. Those players should have the mentality that their jobs are always on the line and they constantly should be trying to impress the coaches.

I had to laugh as I watched this. It was the complete opposite of the 2017 Eagles. Steven Means got a contract extension last August. He was going to be the fifth defensive end on the Eagles and wasn't projected to play a lot of snaps, but the team valued him enough to want him for 2017 and 2018. Why? He is a great practice player.

Means understands who he is. This is Means' fourth NFL team. He was a late-round pick. Means is not guaranteed anything. He uses that as motivation and then practices as if his job is on the line every single day. That helps make him better. It also makes his teammates better.

By going all out in practice, Means helped Lane Johnson and Halapoulivaati Vaitai get ready for Sundays last year. Johnson is the best right tackle in football, and Vaitai got better as the season went along. Means didn't play in the Super Bowl, but he was part of that win. He did everything he could to help his team.

All 63 players matter. That is the 53 men on the roster and the 10 on the practice squad. They can all make a difference.

Just this past week, Jim Schwartz went out of his way to praise cornerback De'Vante Bausby.

"I'm excited about him. We're all excited about the contributions he made to our team last year, and what he can do this year," he said. "Again, his contributions were behind the scenes last year. But we have a lot of guys that have an impact on Sunday that might not be playing. He worked the offense hard last year. I think those guys have respect for him, and I know our coaches have respect for him."
