Tannehill played quite a bit better last year than he did the year before overall even though the OL was much worse. And the one place that the poor OL showed up in his stats besides the sacks was his deep ball. His QBR on passes over 20 yards was quite good in 2012 when Jake Long (who didn't play that well but, was still way better than Martin and Co) was the LT. While it would be simplistic to say it had to do mostly with the poor OL play, it certainly contributed. Wallace's drops and the poor timing of the first year throwing to a speedy receiver also contributed. Having another full off season with Wallace and a hopefully much improved OL should show us what Tannehill is truly capable of.
