As far as Ndamukong Suh can tell, there's a fine line between a good, aggressive play and a penalty. After a season-and-a-half of flags and fines, Detroit's star defensive tackle met with NFL Commissioner Roger Goodell on Tuesday. Suh requested the session in New York at NFL headquarters, and both he and Goodell said the visit was productive. On Wednesday, Suh spoke with reporters at Detroit's practice facility and said he doesn't expect to alter his style.
