Martin tells Buffalo defenders what's what.
This will probably be an unpopular opinion, but I expect Jonathan Martin to be much improved at left tackle in 2013.
First, consider his pedigree. He played 37 of 39 games at left tackle at Stanford, so he's familiar with the position. A reliable run-blocker, Martin's largest identified weakness coming out of college was his inability to handle speedy pass-rushers.
That was proven to be true when he switched to left tackle for the remaining five games of 2012.
According to Pro Football Focus (subscription required), his pass-blocking graded worst at left tackle against San Francisco's Aldon Smith (-4.7) and New England's Chandler Jones and Rob Ninkovich (-2.0 and -2.5 in two games).
However, he showed marked improvement against Jacksonville and Buffalo (-0.6 and 0.0, which is more or less the baseline or average).
In other words, Martin was mostly average at left tackle except against pretty good to phenomenal pass-rushers. That can easily be fixed.
With a full offseason to soak in the blocking schemes, reacquaint himself with the position and bulk up, Martin should be able to elevate his game to average to pretty good. Moreover, he's got quick enough feet to keep up with speedy blitzers; he just needs some technique work.
Remember, the Dolphins don't need an elite left tackle to win. They only need a pretty good one. Martin should provide that in 2013.
