Watch out for wide receiver Desean Jackson when he cuts to the inside or curls to the outside.
Be even more alert when the game is on the line and the Eagles have to go deep and you're a cornerback trying to cover the speedy Jackson one-on-one.
Since his first practice at training camp July 30, the second-year Jackson has dusted every cornerback that's tried to cover him.
Jackson, coming off team highs in receptions (62) and yards (912), has enjoyed getting passes thrown his way and being in the spotlight and has proclaimed himself without a doubt the Eagles' No.1 receiver.
Hard to argue with him.
''I'm not calling the plays, not scheming anything up, but as many balls that come my way, I'm going to catch them,'' Jackson said. ''The biggest thing is just being consistent and I'm going through this camp being consistent, working hard, putting the work in because there is no substitute for the work that you put in.''
