The New Orleans Saints continued to revamp their roster Friday, and their moves had ripple effects throughout the AFC East and beyond.

The Saints made their third trade of the week, sending wide receiver Kenny Still to the Miami Dolphins, who a few hours later traded receiver Mike Wallace to the Minnesota Vikings.

The Saints also signed C.J. Spiller, who was replaced in Buffalo by a similarly skilled player in former New York Jet and Viking Percy Harvin.

The running back market, which had seen five key players move this week, remained active Friday as Spiller signed with the Saints, Darren McFadden replaced DeMarco Murray in Dallas and DeAngelo Williams landed in Pittsburgh, where the Steelers also were busy signing quarterback Ben Roethlisberger to a new contract.

The Saints got the snowball rolling with their third trade of the week, sending the promising young Still to the Dolphins for linebacker Dannell Ellerbe and a third-round pick in this year’s draft.

The Saints now have traded tight end Jimmy Graham, guard Ben Grubbs and Still while adding Spiller (four years, $18 million), Ellerbe, center Max Unger (in the Graham deal) and cornerback Brandon Browner.

After securing Still, Miami got to work looking to trade Wallace and reportedly ended up shipping him and a seventh-round pick to the Vikings for a fifth-rounder.

The Vikings had pursued Wallace in 2013 and reportedly offered more money than the Dolphins, but he chose the warmer climate of South Florida over frigid Minnesota winters.

He lasted just two seasons of his five-year, $60 million contract with the Dolphins and will count $6.6 million against their salary cap in 2015.

Wallace should be the Vikings’ most explosive receiver since Harvin was traded to Seattle in 2013, and now Harvin is on his fourth team in three years after agreeing with the Bills on a one-year deal reportedly worth $6 million.

Harvin is the second explosive offensive player the Bills have added this week — they traded for running back LeSean McCoy on Tuesday.

McCoy was replaced in Philadelphia by Murray, and the Cowboys replaced him, at least partly, by agreeing on a two-year deal with McFadden.

McFadden spent his first seven seasons with the Oakland Raiders but had only 1,249 total touches because of durability issues.

Williams, the Carolina Panthers’ career rushing leader, also signed a two-year deal, joining Roethlisberger’s Steelers.

Roethlisberger, 33, signed a new five-year contract Friday and talked about adding more championships to the two Super Bowls he already has win with the franchise.

Smith replaced Orlando Franklin on a deal will be worth $5.65 million, according to ESPN’s Adam Schefter.
