What I meant was the QB's contribution by himself. The average expected finish in the league is 8-8, and the typical play of both Tannehill and Osweiler -- by themselves (without considering other aspects of a team) -- doesn't make a team appreciably better than 8-8. As an aside, speaking of the defense, the team pulled off a minor miracle today, considering that it surrendered an opposing passer rating of 122.5. There have been 123 games since 2012 in which a defense surrendered an opposing passer rating between 119 and 125. Those defenses won 20 of those 123 games (16%). In 14 of those 20 wins, the defense's own team had a passer rating above that of the Dolphins today (94.9, which is about average and therefore expected). So there was over a 95% chance the Dolphins would lose today's game, based primarily on the defensive performance. The good news is that Cam Wake and Bobby McCain were out, who are obviously key cogs in the pass defense.
