GREEN BAY, Wis. -- Only Dom Capers knows exactly how much time he spent this offseason studying the read-option offense and devising ways to defend it.But we know the Green Bay Packers defensive coordinator and his staff made a trip to Texas A&M in March to listen to the Aggies coaches philosophize about it.And we know Capers spent a day this offseason talking to Wisconsin defensive coordinator Dave Aranda about it.And we know he dedicated at least a portion of almost every training camp practice to working against it.
