The former Cardinal left tackle announced Monday he plans on retiring from the NFL after just three seasons in the league.
Jonathan Martin created a very positive image of the type of football player who could be during his tenure with the Cardinal. Twice he garnered First-Team All-American honors while he guarded the line for quarterback Andrew Luck. He'd eventually impress scouts enough to push his stock all the way up to being named the number 3 tackle prospect at the 2012 NFL draft.
Once in the National League, Martin visibly struggled when the injury-ridden Miami Dolphins found themselves continuously shifting Martin from the left and right sides.
