It's an interesting question, one of which we've chimed in before.
On one hand, some teams don't have that big a rotation and can get by without the extra players, but what happens if there are injuries or transfers. Also the burnout factor -- not just games, but practices take injuries.
And some folks argue that if recruiting is an inexact science to begin with and what happens if you get too many players? That leads to less PT, unhappy players and more transfers.
Out in South Bend, MM currently has a roster of 12 players, 11 of whom are on scholarship (walk on Kaitlin Cole is out for the year). McGraw is on record as having said she prefers using 12 as an optimum roster size.
Right now, if the 2019-2020 season were to start, the Irish would have 9 scholarship players (7 returnees, two verbal commits) and Ms. Cole returning from injury. Depending on what happens in Mid-November, Coach McGraw might get two more commits. Then again, she might get one or none. If the last sentence occurs, that will be a very thin and trim roster to start a season with, for sure. As a result, I think that will make for a very aggressive 2020 recruiting season..as if they're not aggressive enough now
