The NFL preseason is not about wins and losses. It exists to help NFL teams evaluate players and to help to make sure that the team puts together the best roster of 53 players that is possible.
Player evaluation can come in many forms, and statistics rarely tell the whole story in the NFL. This is especially true in the preseason when some players are playing against starters, while other are playing against guys who will be out of the league before Week 1. The solution to this is to use analytics, or metrics, like the performance ratings created by the guys at Pro Football Focus.
Here I will be addressing eight things we learned about the Seahawks, and I'll be augmenting what I saw in my tape study with analytics where appropriate.
