The San Francisco 49ers had the best offensive line in the NFL when they played in the Super Bowl a couple of years ago.
Here’s how I grade that offensive line player by player:
LT Joe Staley: A. The best offensive tackle in the league in 2012.
LG Mike Iupati: A-. One of the best left guards in the NFL along with Evan Mathis of the Eagles and Ben Grubbs of the Saints.
C Jonathan Goodwin: B+. One of the ten best centers in the league.
RG Alex Boone: A-. One of the best right guards in the NFL along with Marshall Yanda of the Ravens and Brandon Moore of the Jets.
RT Anthony Davis: A-. One of the three best right tackles in the NFL along with Andre Smith of the Bengals and Sebastian Vollmer of the Patriots.
Here’s how I grade the 49ers’ 2015 offensive line:
LT Joe Staley: A-. One of the five best left tackles in the league along with Jason Peters of the Eagles, Joe Thomas of the Browns, Andrew Whitworth of the Bengals and Tyron Smith of the Cowboys.
LG Brandon Thomas: C-. Former third-round pick who hasn’t played football in more than a year. Tore his ACL in a pre-draft workout. Tore his other ACL in high school. May need time to re-acclimate himself to the sport.
C Daniel Kilgore: B. Played well last season before breaking his leg. Played especially well Week 3 in Arizona against the Cardinals and Week 5 at home against the Kansas City Chiefs. Has started only seven games during his four-season career. Can he hold up for 16 games?
RG Alex Boone: B+. Missed training camp last season — still was one of the ten best right guards in the league. Hasn’t had a dominant season since 2012.
RT Anthony Davis: B+. Declined in 2013 (plus-5.8 grade, down from plus-19.0 in 2012). Missed nine games in 2014 and seemed slow in pass protection. May no longer be one of the ten best right tackles in the league.
