Having a team full of stars is great, but what happens if that player suffers an injury? Maybe that player needs to take a snap or two off. You can’t leave your team exposed by weak depth.
The Dallas Cowboys have this issue regarding their linebackers. The starters are great, but if one suffers an injury, it becomes a huge problem. The Cowboys need linebacker depth.
When you look at the lineup, you can see the starters are great. The trio of Sean Lee, Leighton Vander Esch, and Jaylon Smith forces the offense to pick which Pro Bowler they want to be tackled by.
