Learn something new every day...I don't doubt the freshman rule but the only question I have regarding your reply is: why is rebounding the only stat that they have seperated by pre and post '73? I would think that all stats would be effected and seperated....yes? Really weird huh? or maybe I'm just confused. check out the link to the on-line booklet I saw the stats in. after you get to the page the booklet is located, click on the "tournament" its a pdf file, depending on your browser you may need to download it from NCAA.COM ,so you'll need adobe or equal. scroll down to the rebound section..

I found the booklet pretty informative and in depth so I decided to keep it for reference. If your a stat junkie like me I'm sure you'll like it.
