Percy Harvin will not play Sunday against the San Francisco 49ers. This could be a huge relief 49ers defense.
Seattle, already rolling on offense, would have gotten another extremely talented offensive weapon. Harvin can play just about anywhere—slot, outside, backfield—and is always dangerous. His combination of size, speed, athleticism, and hands—not to mention kick-return ability—strikes fear into opposing defenses.
Nevertheless, San Francisco should not come into the game with a mindset of “being relieved.” The Seahawks, even without Sydney Rice or Percy Harvin, are loaded on that side of the ball. With a duel-threat quarterback, the 49ers have to play run and pass on every down anyway, even with out Harvin. The emergence of Tramaine Brock and return of Tarell Brown will help against a still-strong receiving corps. Having 3 solid cornerbacks will be quite helpful.
The 49ers defense has been much better this season compared to previous ones about not giving up big plays—Chris Culliver, for all his upside, gave up a lot of them. Harvin would no doubt have helped Seattle, but his absence will not be the difference. Tthe Seattle offense is still good. This game will be won or lost in the trenches.
