Westbrook, Makurat, Bueckers and Williams are all capable outside scorers. Saylor hasn't played a single college game yet, so whether she's a good 3-pt shooter who's coming into the season late (and just started practicing with the team 10 or so games into the season) is TBD.
Like I said...I don't see her playing when Mir is probably ahead of her in the "readiness" chart. And if Mir did lose minutes to Saylor this year, I fully expect her to be apartment shopping somewhere other than Storrs next season (which she might anyway).
