Lorenzo Neal never gets the credit he deserves for his blocking prowess.  But everywhere he goes the tailbacks rush for big yardage by following behind his lead blocks.  Last season the Chargers even threw him some bones by giving him the ball some.  He played in 16 games (11 starts) last season and he carried the ball 29 times for 140 yards (4.8 ypc) with 1 TD run and he caught 17 passes for 83 yards (4.9 avg).  He has now played in 210 games (118 starts) in his NFL career and he has carried the ball 201 times for 750 yards (3.7 ypc) with 6 TD runs and he also has caught 184 passes for 1,028 yards (5.6 avg) with 11 TD grabs.  Andrew Pinnock will be the backup for the Chargers at fullback this season.  He played in 3 games (0 starts) last season and he carried the ball 4 times for 25 yards (6.3 ypc).  He has now played in 32 career games in the NFL (0 starts) and he has carried the ball 14 times for 55 yards (3.9 ypc) and he has caught 3 passes for 26 yards (8.7 avg).
