Iowa basketball coach Fran McCaffery snagged a major victory Monday when South Sioux City Nebraska star Mike Gesell verbally committed to the Hawkeyes.  Gesell, a six-foot-one point guard, had narrowed his choices to Iowa, Nebraska and Stanford.  He also had offers from Iowa State, Creighton, Northern Iowa, Drake, Utah and Harvard.  The all-stater has led his prep team to the last two Nebraska Class B state titles.  As a junior last season, Gesell averaged 25.2 points, 8.2 assists and six rebounds per game.  Most of the major recruiting services list him as a top 100 recruit.
