COSTA MESA, Calif. -- Gus Bradley has seen it before.
The Los Angeles Chargers defensive coordinator served in the same role with the Seattle Seahawks when the Legion of Boom emerged eight years ago, and he now oversees the creation of another talented secondary.
But while the Seahawks had a unique blend of bravado, size and length, the Chargers have relied more on quickness, playing with precision and anticipation.
"It's really hard to compare this group to that group because each group has its own personality, and that's what drives them," Bradley said.
