the Minnesota Vikings have agreed to trade receiver Percy Harvin to the Seattle Seahawks for draft picks, including Seattle's first-rounder in 2013, a seventh-rounder in 2013, and a mid-round pick in 2014. He's played all 16 games in a season just once -- in 2011. Harvin is guaranteed a $2.755 million base salary in the last year of his rookie deal. According to a recent Yahoo! Sports report, Harvin believes himself in the same class as Detroit's Calvin Johnson, and wants the same kind of contract. Johnson signed an eight-year, $150.5 million contract in March of 2012, and averages $16.5 million per year.
