What do you consider small? Brock's not heavy enough or 6 foot is too short to play at this level. There's a lot of 6 foot and under players at this level, all over college basketball.
The guard that you want Iowa to recruit is not going to come to Iowa, you know that right! Fran is already playing 4 forwards at the same time and it's not working and in fact Fran's best players over the last 14 years have been forwards, very few centers, and even fewer actual point guards. Brock is a true point guard and occasionally will as you and others have said "get sucked under the basket". By the way you and others are extremely happy with the defense that Krikke plays, is that an arcuate assessment?
