First, it’s crazy to characterize NESCAC athletes as merely solid high school starters. Most recruited NESCAC athletes were absolute superstars in their sports, not just at their high school, but regionally. For example, last year’s Williams’ women soccer team, which won the 2016 national championship, had three STATE Gatorade players of the year on the squad. They’ve enrolled yet another for this fall. In basketball, most of the significant contributors in NESCAC were all-conference / all-region and many made all-state squads. The best player on 90 percent of high school sports teams couldn’t make a significant impact at any NESCAC program, in any sport.
Second, you really do have to look sport-by-sport, and school-by-school. The very top NESCAC men’s basketball programs, which compete at the very highest level of Division 3 (Williams, Amherst, and Middlebury) all have multiple players who could contribute at schools in the bottom third of the Ivy League, and in many cases were recruited by some Ivy League programs. With rare exceptions (like Duncan Robinson, who transferred from Williams to Michigan where he has been a starter) couldn’t, however, compete at the top few Ivy programs in any given year.
Football is different. Any Ivy league team would absolutely crush even the best NESCAC squad. There is just a huge difference in talent and also in off-season training and physical development. But in tennis, on the other hand, if you look at both the men’s and women’s recruits that the top few NESAC programs (again, Williams, Amherst and Middlebury most years, along with Bowdoin some years) bring in, they have very similar rankings and recruiting profiles to the recruits the bottom few Ivy league programs bring in – there just isn’t a dramatic difference there.
Turning now to the advantages of NESCAC vs. the Ivy League, some of which have already been covered:
(1) In NESCAC, you will have the chance in MANY sports at MANY schools to compete for NCAA championships, year after year. That is rarely the case in Ivy League athletics (with some exceptions, like lacrosse). A lot of folks would rather get to play in 1-2 D3 final fours and 3-4 D3 NCAA championships over four years than playing for a mid-tier Ivy League program that never sniffs an NCAA D1 tournament. NESCAC is, across the board, by far the most dominant league in D3 athletics, whereas Ivy is in the bottom tier of many D1 sports.
(2) The allure of playing multiple sports. Many, many NESCAC athletes play multiple sports. Many of them could have gone Ivy, or to another D1 school, if they agreed to focus on only one sport. It’s far harder due to competition, longer seasons, and tougher in-season time commitments to play multiple sports at the D1 level, and you have to be a truly spectacular athlete to even have a prayer of doing so. At NESCAC schools, on the other hand, a huge number of athletes compete in multiple sports.
(3) The ability to engage deeply in campus life outside of athletics and academics. You’ll routinely see NESCAC athletes as editors of the campus paper, leaders in student government, members of campus music and arts groups, etc. etc. That’s much tougher as a D1 athlete.
(4) Earlier opportunity for significant playing time. Many NESCAC athletes can compete or even start for Ivy programs, but might have to wait a few years, while at NESCAC they can start as an underclassman.
Now, I’m not saying that the majority of NESCAC athletes could have played at an Ivy. But across the top athletic programs in NESCAC, there are a substantial number of athletes who chose to go D3 despite D1 offers or serious interest, for many very good reasons.
