“Are the Seahawks without hope if they’re without Will Dissly?”
Sure.
If the Seattle Seahawks can win on the road against a decent team win playmakers on both sides of the ball, without two important (crucial!) starters, then they can win any game between now and season’s end. If Wilson remains in the MVP race and the defense hounds receivers? They’re a playoff team.
But it’s not immediately obvious that they’re a Super Bowl contender without a strong second receiving option who also happens to be their red zone wizard, and without the most important position on the O-line filled.
