I really like Moore and think she’s a star of the future, but even at her peak earlier in the season I don’t really think she brought anything more than Eddy has done consistently week in week out. In a year or two maybe.
Versatility is not that important for a four match test series in my opinion. Players don’t need to be rested and realistically only about 10 of them will probably even take the court. Selecting squads for a tournament is very different from a series.
