Much to the dismay of many, Zack Martin has decided to use what leverage he has in order to hopefully have his current contract reworked so that his pay coincides with the other top players at his position. Currently he is the ninth-highest paid offensive guard in the league, despite being arguably the best player his position and one of the best overall offensive lineman in the entire NFL.
Love it or hate it, Zack Martin is using the only leverage he has by deciding to stay away from training camp. In so doing, his absence causes quite a few ripple effects though.
