Marshall alters Dolphins immediately

For years, fans have begged the Miami Dolphins to acquire a downfield threat.

They Dolphins finally have done so, acquiring Brandon Marshall from the Denver Broncos for a 2010 second-round draft pick and what sources tell ESPN's Adam Schefter will be a second-round pick in 2011.

Marshall's arrival will change Miami's offensive dynamic immediately.

Chad Henne, who played with a receiving corps designed for Chad Pennington's soft-toss arm, has a legitimate deep target to stretch the field and snag jump balls in the red zone.

Marshall has been the NFL's most prolific receiver, topping triple digits in receptions three times in his four NFL seasons. Over the past three years, he has averaged 102 receptions for 1,237 yards and eight touchdowns.

Miami's top two receivers in the past two seasons have aggregate numbers not substantially better.

Last season, Davone Bess and Greg Camarillo (two undrafted players) combined for 126 receptions and 1,310 yards with two touchdowns.

In 2008, Ted Ginn and Camarillo combined for 111 receptions and 1,403 yards with four touchdowns.

The Dolphins had a single 1,000-yard receiver in the aughts. Chris Chambers gained 1,118 yards in 2005.
