Lost by 18, not to one of the better teams in the tournament, but lost by 18 to a team that barely made it into the tournament. And this has been indicative of the last half of the season, where ISU just lays offensive eggs against not really good teams. A similar thing was going on last year.
There is something that needs fixing beyond talent. There is an issue with the strategic, fundamental, and mental preparation in the offensive game that the coaching staff needs to figure out. When you can beat BU three times, KU, and UT, your offensive shouldn't get shut down by a team that had to "play-in" to the tournament. When the simple, basic offense doesn't work, this team just falls apart.
