Philip Rivers was tied for eighth in the NFL last season with an average of 7.9 yards per pass attempt, but he is tied for 21st this year with an average of 7.1 yards per attempt.
San Diego was tied for 12th in the NFL last season with an average of 4.3 yards per rushing attempt. The Chargers are tied for 18th this season with an average of 3.9 yards per attempt.
San Diego suffered a major loss in free agency when Vincent Jackson signed with the Tampa Bay Buccaneers. Jackson led San Diego in receiving yards and touchdown receptions during the 2009 and 2011 seasons. Jackson had nine TD receptions last year and averaged 69 receiving yards per game.
Former New Orleans Saints wide receiver Robert Meachem was brought in to be Jackson’s primary replacement. Meachem is averaging about 32 receiving yards per game this season and is on pace for five TD receptions. Jackson is averaging 98 receiving yards per game in 2012 and is on pace for 13 TD receptions.
Ryan Mathews averaged 4.9 yards per rushing attempt last season to go along with 78 rushing yards per game. Mathews broke his clavicle in a preseason game against the Green Bay Packers on August 9, 2012.
Mathews missed the first two games this season and is at 4.5 yards per attempt to go along with 65 yards per game.
San Diego’s offensive line allowed 30 sacks last season which ranked eighth in the NFL. The offensive line has allowed 18 sacks through six games this season which is ranked 26th in the league.
San Diego’s front office took a risk by letting Jackson sign with Tampa Bay. San Diego had a 32-20 record with Jackson from 2008-2011 while they were 6-6 without him during this time.
The loss of Jackson along with an awful offensive line could prove to be too much for San Diego’s offense to overcome this season.
