Whether it's Michael Vick, Cam Newton, Fred Jackson or Frank Gore, it seems like every week the Redskins' defense faces a challenge against an elite offensive player.
On Sunday in Miami, wide receiver Brandon Marshall is the Dolphins' playmaker in the passing game.
The dynamic All-Pro receiver has caught 46 passes for 644 yards and two touchdowns so far this year.
The Redskins have not played Miami since 2007, but they have seen Marshall more recently, when he was a member of the Denver Broncos.
During Week 10 of the 2009 season, the Broncos came to FedExField and Marshall turned in an outstanding game. He hauled in five catches for 134 yards and two touchdowns.
His two scores turned out to be the Broncos' only touchdowns, as the Redskins rallied to win 27-17.
Redskins cornerback DeAngelo Hall played against Marshall that day. As part of his preparation for this Sunday's matchup, he watched film of that game.
"He just double-moved us," Hall said. "There was nothing special he did, we just bit on double-moves and he got behind us a couple of times."
Double-moves aside, Hall is fully aware of the challenges that the 6-5, 230-pound Marshall presents the Redskins' defense.
"He's a good receiver," Hall said. "Anytime you have a guy that big, that physical, can run that well, can catch every ball you throw, he is going to be a tough cover."
Added Hall: "Myself, Josh [Wilson], Kevin Barnes, whoever gets the chance to cover him, we are going to try our best to get our hands on him and try to be as physical with him as he is going to be with us."
Marshall's play-making ability is not lost on defensive coordinator Jim Haslett, either.
"His size is a starting point," Haslett said. "He has great physical skills, obviously. He has great catch ability, and his run after the catch is outstanding. He's hard to bring down. He's such a big guy and he's fast, so he has great qualities."
Head coach Mike Shanahan is more than familiar with Marshall. When Shanahan was the Broncos' head coach in 2006, he drafted Marshall in the fourth round.
Shanahan immediately saw something special in Marshall. He shined in the Broncos' very first practice.
"You could see his strength, his speed, his quickness, and his hands," Shanahan said. "You could just see the first time he went one-on-one in OTAs. that he had something that most players don't have."
