The run blocking hasn’t come along like the Pass Blocking.
Your left tackle has six starts, the Center has 16 , RG has three starts total in his career and the RT has three starts at that position.
Tomlinson has two starts at LG with the Packers but has 164 starts with 175 games played.

Every RB was tackled behind the line. Dallas was on the Packers side more than the Packers moving them in the run game.
No one was getting to the second level and the first wasn’t much better,
With the size on the right side they should get some push. Run blocking has to be a well oiled machine and right now the whole operation is sloppy.

Jacobs is just that talented to do more with less than the others but it’s a tough go for any RB.
