The average career length of an offensive lineman drafted in the 1st round between 2000 and 2010 with 5 or more Pro Bowl selections is 12 years.
I chose this decade because it is the most recent with all players retired. I chose those with 5 or more Pro Bowls because this is also a good measure of durability and Zack Martin fits this profile.
There were several players in this category whose careers were from 13 to 15 seasons.
Since 1970, there has been 80 occasions in which a former 1st round pick offensive lineman was selected to the pro Bowl in their 10th season or beyond.
Zack will be entering his 10th season. It is not unusual at all for elite offensive linemen to enjoy lengthy careers with a high level of production.
A smart GM wouldn't have waited for Zack Martin to communicate his discontent. One of the issues that Jerry Jones has always struggled with is the notion that there is some kind of "victory" when elite players are not getting paid up to the level of their productivity compared to others. Seriously, what did Jerry expect?
If a player doesn't live up to his contrtact, fine, get rid of him. However, don't be a hypocrite and refuse to compensate those that earned it through their elite level of play.
Throughout Jerry's "career" as a GM, he has consistently overpaid the wrong players and kept them longer due to issues like sentimentality, poor evaluation or even the flawed perception that the more you pay them, the harder they will work.
There is a long list of players whose production dropped a split second after signing their contract. Zack Martin has never appeared to behave in that way.
