Coming back for his senior year and a dominant performance in the Senior Bowl helped boost his draft stock up into the late-middle first round. He’s been evaluated as undersized, having short arms and not being strong enough to handle NFL-sized defensive tackles in the interior line. This would pretty much count him out as a guard.
He is, however, quick, agile and possesses good body control, thought to pick up blitzers instinctively, and rarely loses position. Combine that, his performance on the outside in the Senior Bowl and his high football I.Q., and he can be considered an intriguing prospect at tackle.
Right tackle is likely a good place to put him as long as his learning curve and adjustment into the pros doesn’t stunt his growth.
Based on his technique and fundamentals he might even be coached up to play LT in the future.
From CBS Sports:
Though Martin lacks the prototypical size of a modern NFL tackle, he has exhibited impressive technique and better-than-average strength, and after a strong Senior Bowl showing, many scouts believe he could not only play on the outside at the next level, but could do so very well.He’s instinctive, tough and technically sound despite lacking elite athleticism, and his biggest appeal to NFL scouts may be his versatility as many believe he could step in and succeed either at tackle or guard, as a pro.
