If you have had a casual conversation with someone about this Sunday’s Dallas Cowboys game on the road against the Seattle Seahawks, then the subject of the latter’s famed “Legion of Boom” likely come up. While the Seahawks do feature Jamal Adams in their secondary, the reality is that overall that group is hardly what it once was at its peak. We all tend to fall into patterns when it comes to position groups for various NFL teams as we look at the league as a whole, and the same certainly bears true for the Cowboys as far as how others see them.
