BLOOMINGTON, Ind. — Iowa’s good soldiers walked into the postgame news conference and gave the same answers you’d expect after a 24-21 loss at Indiana. They gave credit to their opponent. Their failure on individual plays had everything to with execution or miscommunication, not the game plan or coaching staff. It’s a brave front they put up once again as part of their third straight loss. “It just comes down to execution,” Iowa quarterback James Vandenberg said.
