It's because Joe Brady isn't an O-line or RBs coach, just a WR coach only by position. He knows nothing about about the trenches, but our WRs aren't producing either, which suggests he has poor knowledge about any part of the offense. An offensive coordinator needs to have an O-line scheme to not only run block, but to pass protect, with a million assignments for each position, for different defensive looks. Brady's offensive plan looks like, " it's either this way or no way". Which we seem to be going to nowadays.
