You cannot look at one game and think that is the reason for anything else. Every game is different and every outcome is random. What will you say if they lose to the Jets next week?
Dolphins had 2 really good/elite WRs and they could barely make the playoffs.
Last year the Vikings had one of the best WRs and got knocked out in the first round of the playoffs.
Bengals had 2 elite WRs last year and they didn't make the playoffs.
