Plum Street - there had been a fair amount of rumors regarding academic issues and the Harvard basketball program. It was discussed and addressed to the satisfaction of the schools. The Ivy League has extremely strict rules which are covered by a binding contract between all the member schools. The rules cover both academic requirements for individual athletes, each team, as well as the overall athletic programs. Yes, there are individuals who are admitted that would not ordinarily be accepted at an Ivy. Those with lower admission credentials need to be offset by other athletes. The standards are generally set forth by the Ivy League A-1 Index. The presidents of each institution are the decision makers for these issues - not the athletic directors. So, while you will see individual athletes at Ivy schools who generally would not be admitted, they still must meet reasonably high academic standards. Many years ago it was more of a "gentleman's agreement" between the Ivy schools. That was changed and there would be serious consequences if any member school was caught violating the current contractual agreements. Since the Presidents are actively involved this is not realistically a problem.
Both Bamba and Carter are good students who would not have any issue qualifying pursuant to the A-1 Index.
