UConn is in a very nice position right now with both returning players as well as incoming recruits and commits. Geno can afford to be picky.
With 4 talented G/W's in next year's class, I have to believe that Geno will gladly take CW in 2018, but if she decided to go elsewhere, UConn would be just fine. With Charli Collier already committed, I do believe that Geno would consider another true 4/5, but it would likely be a really good player, i.e. Ono, Smith, etc.
With UConn working hard on Brunelle for the class of 2019, if she were to commit, UConn would be in really good shape through 2021, even if they don't get anyone else, although I expect there will be other signings in 2018 and/or 2019.
