The veteran center has been the anchor for this offensive line and helped provide stability in 2014 during the transition as the coaching staff tried to find a starting line that worked well.
PFF provided a case for Kalil on why he should have made the list and why he shouldn't have:
Argument for Top 101 inclusion:
Ryan Kalil had the third-highest run-blocking grade of any center last season, and the two players above him both made the list. He was the anchor of a surprise unit in the Carolina offensive line that performed much better than expected, and helped the team get to a 15-1 regular season record (and all the way to the Super Bowl).
Why he isn’t in the Top 101:
Kalil surrendered three sacks and 18 total pressures, a mark bettered by nine other players at his position, and had his three worst games of the season during the playoff run, adding 12 pressures to his résumé and culminating in the Super Bowl in which he allowed five hurries.
Kalil was drafted by the Panthers in the second round of the 2007 NFL Draft and has been the primary starting center since his second season. He has made the Pro Bowl five times, including this past season, and has missed only one regular season game the past three years.
