That's two years old, couldn't find an updated one, but 58% of Brady's passes were less than 10 yards, ranked #1 in the NFL. I guarantee not much has changed.
The entire reason Edelman is seen as one of the best slot guys is because he's in NE, that's all they do. He's the #1 WR on the team.
Not that it means they are needing Cruz, it just seems like the type of player NE would look at to me.
