Longtime Dallas Cowboys guard Zack Martin originally announced his retirement in late February after telling the organization he was planning on calling it a career. On Wednesday, the 11-year pro made his retirement official after penning a lengthy letter on The Players’ Tribune.

FRISCO - Zack Martin's decision to retire from football wasn't a roster-related shock, as the Dallas Cowboys legendary right guard making mention to us of it as a possibility last summer at training camp in Oxnard.

Guards don't get any better than the newly retired 34-year-old. Imagine how much better the Cowboys would be if the team was run in the manner that he played.
