Programs need to get the best available players and there are plenty of "undersized" players that are a lot more productive then a lot of taller ones. Of course you would like to have 6-5 players that are athletic and multi- dimensional but there are not many of those. As an example of two BW players that come to mind is six foot flat Kash at LBSU that was first team all big ten in her lone year after LBSU and currently sub six foot Travis from UCSB now at Wisconsin. She is picked by many to be a starting pin at that top 5 school. Of course size maters if you have everything else.
