RENTON Kendrick Lamar is all of 5 feet 6.
But he was a giant to the surprised Seahawks on Monday.
The Grammy Award-winning rapper, whose songs are a regular part of the sideline DJ’s rotation during practices here, walked into the center of the field immediately after three air-horn blasts ended training camp’s second practice. Wearing a hood on the sunny, 78-degree day, Lamar joined All-Pro linebacker Bobby Wagner to “break the team down.” That’s the players’ term for leading them in raising hands inside a giant mosh pit and leading a roaring chant that ends each workout.
