I am not sure we read that article the same way. I think that the references in the article (http://www.thecrimson.com/article/2003/6/27/ivy-league-caps-athletic-recruiting-the/) to football being dealt with separately address the AI averaging, not the number of slots. As far as number of slots, the article states directly
What is more, if you review the 2011 Ivy Manual, and add up the travel squad limits for the recognized sports (including football and non “Ivy championship” sports like hockey) and multiply the total by 1.4 you get 230, which is the number cited in the Yale Daily Herald in 2012 as slots “given” by the Ivy League (http://yaleherald.com/homepage-lead-image/cover-stories/always-outnumbered-never-outplayed/). For this reason, it appears to me that the football travel squad is used to calculate the multiplier, even though football is separately designated as receiving slots for support in excess of this number every year.
This is important for a couple of reasons. One, we know that football gets 30 “slots” a year, even though their multiplier number is 21.7, so the AD has to account for those extra 8.3 slots elsewhere. Two, there is consistent reporting that schools do not use all of their allotted slots. @fenwaypark has cited some reporting in the Brown Daily Herald that Brown limits itself to 205 (if I remember correctly) such slots, and @bluewater2015 cited an article up the thread disclosing that Yale issued 171 a few years ago. So in my opinion, it is highly unlikely that any more than a handful of coaches at any given school are given their entire allowable allotment of likely letter slots in any given year.
I think this is true, although I would believe that the vast majority of matriculating athletes who receive support for a likely letter are rostered during the first semester of their freshman year. But the intent of setting out the numbers in the original post was not to show how many likely letter athletes there were in each sport in the freshman class at each school. It was to highlight the maximum allowable under the rules, and the fact that the rosters include more freshman than we can reasonably anticipate there are slots for, even in the spring sports. I am assuming that the fact that these kids are rostered, especially in the spring sports, indicates that there was some recruiting going on prior to arrival on campus.
