Calvin Johnson's nickname is enough to scare opponents, even if he's not finding the end zone with regularity.
The All-Pro wide receiver will try to catch his first touchdown pass from Matthew Stafford this season when the Detroit Lions (1-3) visit the Philadelphia Eagles (3-2) on Sunday.
''When they give you the nickname `Megatron,' that means you're pretty good,'' Eagles coach Andy Reid said of Johnson. ''He's a really good player.''
Johnson has a tough challenge going against a secondary that features a pair of accomplished cornerbacks: two-time All-Pro Nnamdi Asomugha and Dominique Rodgers-Cromartie, a 2009 Pro Bowl pick. Rookie Brandon Boykin may even line up against Johnson at times.
''These guys have corners that can play,'' Stafford said. ''You look at them on tape, they're shutting guys down.''
Whatever the Eagles plan to do to cover Johnson, they're not letting on.
