The New York Basketball team announced that, beginning next month, they plan to include different coaches for their training in order to win the upcoming championship.
The major issue of this sentence is whether to treat "team" as singular or plural subject - both uses are correct.
In my opinion it would be better to treat "team" as a singular because there is no reference to the plurality of the team. Neither members are mentioned nor their number. On the other side, the intented plan concerns all team unitedly as one body. Still on the other side, team itself cannot make decisions, unlike its members, what would call for "they". Please specify what the GMAT wants.
