There is no hiding the grin on Percy Harvin's face these days.

After a difficult two seasons that saw Harvin miss 23 games overall due to ankle and hip injuries, Harvin is fully healthy once again and looks ready to explode this season.

And he might just take the Seattle Seahawks offense along for the ride.

Harvin has been unhindered in training camp by the hip injury that limited him to just one regular-season game last year. Harvin said he hasn't felt this good since before his college days at the University of Florida and he's found gears he didn't realize he had.
