They just acquired Silvia Fowles in a 3 team trade (with ATL and CHI) and aside from swapping draft picks they gave up a bench player and a bench warmer.
Silvia has been injured (ego injured sitting out because Della Donne is the starter in CHI) so she should be well rested going into the 2nd half of the season.
I don't see who can beat them in a series this year.
