Given that Iowa may be oversized at the 1,2 and 3 positions and, as a result, perhaps lacking the quickness to contend with smaller and quicker penetrating guards, and perhaps a little undersiized at the 4 and 5, making it difficult to contend with bigger and stronger opponents, is there any chance McCaffrey would consider a zone defense, ala Syracuse, to utilize Iowa's perimeter length and compensate for the lack of a stopper inside? Does Iowa's staff have any history of teaching and utilizing on a continuing basis a zone defense?
