Former Packers’ OLB Preston Smith’s unexpected trade to the Steelers adds valuable depth to the defense, and was surprising to fans alike.

Newly acquired Pittsburgh Steelers (6-2) outside linebacker Preston Smith revealed Wednesday he requested a trade away from the Green Bay Packers (6-3). Smith, 31, cited an unnatural fit in first-year Packers defensive coordinator Jeff Hafley‘s 4-3 scheme.

Preston Smith said he requested a trade and wanted to go back to the 3-4 defense before the Packers dealt him to the Steelers.
