The AI band system is not just used for football. It’s used by the Ivy League athletic conference to establish a common set of rules for interschool competition in Ivy League sports in general, including tennis and golf. A good summary is at https://www.mka.org/uploaded/college_counseling/Publications/AI_Guidelines_Worksheet.pdf . Quoting the summary,
“Every team has an annual ‘quota’ and every athlete within that group is assigned to one of four bands based on his or her Individual AI.”
While Harvard does reduce its usual academic standards for many athletic recruits, many top high school tennis players still do not meet Harvard’s academic qualifications and are not eligible for recruiting due to academic qualifications. Furthermore the coach needs to consider what the team needs, which is not always as simple as ranking. For example, maybe the team needs more good doubles players, rather than singles. Maybe the coach is concerned about getting players who he’s sure will continue through all 4 years. Maybe he wants to establish a personal rapport and be sure that the potential recruit will work well with his coaching style and get along with the team. It’s not a simple as just going down a ranking list.
That said, Harvard and nearly any other college would be happy to get most academically qualified players who are ranked ~100th nationally. It is silly to assume they were admitted because of race, rather than being a recruited athlete who is nationally ranked in their sport.
You can view the number of URMs in the Ivy League athletic conference at http://web1.ncaa.org/rgdSearch/exec/saSearch . In the 2017-18 year, the sum of URMs across all 8 Ivy League colleges are below:
Ivy League URM totals By Sport
Men’s Golf – 1 URMs (black)
Women’s Golf – 0 URMs
Men’s Tennis- 2 URMs (1 black, 1 hispanic)
Women’s Tennis-- 4 URMs (3 black, 1 hispanic)
With only 4 URMs across the entire 8 Ivy League colleges, it’s extremely unlikely that all 4 are on Harvard’s team. Looking at the team roster, is only a rough estimate of race. That said, the players I’m guessing you are referring to are below, along with their recruiting status. All are really stellar recruits that are 4 star or higher. Are you really saying that all who are below 5 star do not have the “athletic pedigree of a legitimate recruit” and must have got in because they are URMs? Harvard averages ~two 5 star recruits or 5 star blue chip recruits per year . It never gets more than three. If Harvard wants to have enough players for a standard team, not everyone on the team can be a 5 star. These 4 possible URM recruits have a better average recruiting ranking the the non-URM recruits, so if anything, it would suggest the non-URMs are more likely to be the weaker recruits.
Erica Oosterhout – 5 star, blue chip recruit ranked 21st nationally, best Harvard recruit of her year
Chelsea Williams – 5 star recruit
Annika Bassey – 4 star recruit
Natasha Gonzalez (only possible URM due to last name, doesn’t look especially Hispanic) – 4 star recruit
