Show and prove: Dolphins' Jonathan Martin

The AFC East blog continues its "Show and Prove" series for players in the division in 2013.

Next up, we take a look at Miami Dolphins left tackle Jonathan Martin.

2012 stats: 16 starts

What he must prove: Martin has to prove that he can make the switch full-time from right tackle to left tackle, which is one of the toughest transitions in the NFL level. Fortunately for Martin, he played left tackle most of his career at Stanford University protecting college teammate Andrew Luck. Martin is a smart player who understands the mechanics of the position. However, he has big shoes to fill replacing four-time Pro Bowl left tackle Jake Long.

Walker’s 2013 outlook: Opinions vary on Martin’s ability to make the switch. I thought he was more consistent on the right side last season and struggled when facing top competition on the left side. The thing I’m most concerned with is Martin’s strength. But Martin did a good job of adding noticeable bulk in the offseason in his upper body. What made Long so good was his consistency. In his prime, Long would go weeks without a bad play or allowing a sack. Martin still has to prove his consistency in Year 2. His development is one of the most important storylines for Miami this season.
