In the last 5 seasons, 14 teams have given up 50 or more sacks. The Dolphins' total of 58 is the highest. The average number of wins by those teams is 6.5. Only 4 teams had more than 8 wins. Those teams were:
2012 Packers (11), 2010 Bears (11), 2009 Packers (11), 2009 Steelers (9).
A few key points:
1. Rodgers is considered by some to be the best QB in the league. He has two of those seasons.
2. The Bears in 2011 only scored 1 point per game more than the Dolphins and Cutler's numbers on the season were very close to Tannehill's. That team was driven by defense. They only allowed 286 points.
3. The Steelers missed the playoffs in 2009. In 2008 and 2010 they went to the SB (won it in 2008). IMO, a SB quality team was done in by SACKS.
4. The Packers, Bears, and Steelers all ran the ball better than the Dolphins.
If you eliminate the outliers of the two Packers seasons and the Bears season, the average number of wins is 5.3.
Of the young QBs that played on those teams, Tannehill was by far the best performer. In 2011, Sam Bradford had a QB rating of 70 and didn't finish the season. John Skelton had a QB rating of 69 in 2011 and 55 in 2012. In 2010, Jimmy Clausen had a QB rating of 58 and Matt Moore had a QB rating of 56.
At this point we can conclude that Tannehill is not as good in his 2nd season as Rodgers was in his 5th or 8th seasons, or as good as Roethlisberger was in his 6th season. Big deal.
Of all those QBs, Tannehill had the worst pass blocking. Of the teams that had records of 8-8 or better, Miami had the fewest rushing yards.
I simply cannot understand how fans can put the majority of the blame on Tannehill.
