So would baseball be a one half helmet sport?
"Helmet sport" was the generalized phrase used but not sure specifically what sports were included. By that definition that could include equestrian, wrestling, fencing and water polo but I don't think that was the intention.
What really matters is how many qualifying athletic 'slots" with Likely Letters each Coach could recommend to Admission. For my son's school, baseball was only 5 Ivy Likely Letter recruits and the other recruits had to get in on their own merit...no standard deviation from an incoming Ivy class. What the general public, faculty and students fail to realize is some of these recruits got in on their own (same as normal students) with minimal pull by the Coach. These recruits were bundled in with the rest of the team. I was told there were many more "slots" for football, lacrosse and hockey athletes just because of the size of their teams or the money they brought in. Lacrosse and hockey are huge among Ivys.
