Both Percy Harvin and Anquan Boldin are headed west after being acquired via tradeThe two NFC West leaders from 2012 each traded for a wide receiver that will address a weakness from last season.

Percy Harvin to Seattle Seahawks

The Seahawks lacked play-making ability from their wideouts last season ranking in the bottom four of the league in receptions (143), receiving yards (2,007) and yards after catch (523).

The trade for Percy Harvin immediately remedies that as Harvin, despite playing in just nine games last season, had 528 yards after the catch – more than the entire Seattle wide receiver corps combined.

Harvin also brings versatility to the Seahawks. Since the NFL/AFL merger in 1970, Harvin is one of only three players to have at least four rushing touchdowns, four receiving touchdowns and four kickoff return touchdowns (Brad Smith and Brian Mitchell are the others).

Anquan Boldin to San Francisco 49ers

San Francisco ranked 21st in red zone percentage during the regular season. During the playoffs, only two 49ers (Michael Crabtree and Vernon Davis) received red zone targets.

By comparison, Boldin was targeted six times this past postseason. He caught six of the targets, four of which went for touchdowns.

2012 Season

Boldin’s arrival in San Francisco could mean more three-receiver sets for the 49ers. Including the playoffs last season, the 49ers used three-plus wide receiver sets 29.8 percent of the time when trailing last season, the lowest rate in the NFL (league average: 59.5 percent).

Impact on Joe Flacco

Boldin was Flacco’s go-to receiver last year. Including the playoffs, he had a 61.7 completion percentage on throws to Boldin and a 48.1 completion percentage on throws to all other wide receivers.

And on third downs in the playoffs, Flacco targeted Boldin 12 times. The next most targeted Raven in those situations was Jacoby Jones with six.
