9) Shaq Mason
After a shaky start to the season, veteran right guard Shaq Mason has positioned himself once again as one of the top offensive guards in the NFL.
His 73.0 overall grade by PFF ranks as 9th best amongst guards in the league, and his contributions to New England's offensive line have been tremendously helpful in a down year for the unit.
Week 12 is the best example of how dominant Mason has been at times this season.
Let PFF explain:
"Mason led all Patriots players in overall grade at 88.1 in the team’s 17-10 win over the Eagles in Week 11. He earned an 84.5 run-blocking grade and allowed just one pressure from 50 pass-blocking snaps."
It would likely take a couple absentee's from the Pro Bowl for Mason to make his way onto the AFC's roster. But that doesn't make him less deserving of a spot in the Pro Bowl.
