Some of Carroll's bold gambits haven't worked out. (Tarvaris Jackson and Charlie Whitehurst, anyone?) Some have provided mixed results. (Sidney Rice, Zach Miller.) But the Seahawks have swung for the fences and connected more often than not. (Marshawn Lynch, Chris Clemons, Bruce Irvin, Russell Wilson, and countless draft picks.)
Harvin is a gamble because of the resources Seattle traded. The Seahawks are an organization built on great draft picks, and now they will have fewer turns at the podium. Harvin also will cost No. 1 wide receiver money to retain long-term. Sidney Rice, who is due $8.5 million in each of the next two seasons, also makes No. 1 wide receiver money. Don't expect Rice to be released this offseason, but his status is year-to-year at this point. It's hard to pay so much money at that position.
The trade is less of a gamble because of Harvin's reported troubles with the Vikings' coaching staff. No one has ever questioned Harvin's toughness, work ethic and desire to win. You can work with a guy like that.
Wilson already is such a unique quarterback to game plan against, adding Harvin just gives Seahawks offensive coordinator Darrell Bevell an endless array of options. The Seahawks have proven expert at finding roles for players on both sides of the ball and accentuating what those players do well. Harvin does a lot of things very well. Based on their track record, I expect the Seahawks to know just how to use him.
