Yes the run blocking schemes need some work, but the line would look a lot better if the QB could complete passes for more than 10 yards. When you have no middle or deep passing game the D packs the box with 8 or 9 guys, mans up on the WRs and fills gaps making it hard to run. The backs made it past the line yesterday but there was no where to go after that point because the D was staying at home, due to the lack of passing game. On pass plays the D can put their ears back and rush 6 guys because there is no threat of getting beat by the passing game. It is easy to game plan for ISU, play the run and make the QB beat you, problem is our QBs have problems with that.
