A healthy Harvin is one of the league's rare difference-making talents. He was arguably the NFL's premier receiver on film early in the 2012 season before going down with an ankle injury.
The Seahawks believe Harvin's return to the starting lineup will make them even more formidable next season than they were as the NFL's dominant team in 2013.
Don't expect the coaching staff to limit Harvin's role in an effort to keep him healthy next season.
The luxury of utilizing Harvin's full capabilities is just one of several reasons that Carroll's squad will be favored to repeat as champs in 2014.
