First, Pro-Bowl isn't the end all be all. There is a popularity aspect of the voting, plus, especially with O-Linemen there can be an element of familiarity with the voting since there is limited statistical evidence to judge from. Don't get me wrong, I'm not suggesting Martin and Smith aren't high quality players, I'm just saying they have been banged up some this year, and this probably isn't among their top seasons. Second, even with two high quality players that doesn't change the fact that they have missed games, and other positions have been relying on back ups and even 3rd teamers to get by. And finally, it's pretty far fetched to think any of us are expert enough on every O-Line across the NFL to create a fair ranking. We see RBs and receivers and QBs across the NFL because they have the ball in their hands and the camera follows the ball, but are any of us really studying the O-Lines of every team? All I know is the O-Line has seemed very average this year. Dak has gotten considerably more pressure from opposing pass rushes than in the past, and although Zeke is having a strong year at RB, it seems the stats aren't built by consistently run after run gaining yards, but rather by several short or no gains followed by 8-12 yard gains. In other words, it doesn't seem that we have many possessions where just pounding the rock works with the O-line dominating to the point every run seems to be for 4-5 yards or more. The running game seems to come more in spurts.
