The 13 FP aren't a major concern given that's just the 3rd time Smith fell under 20 this month, but the Aces upcoming schedule is untenable for fantasy playoffs. If you're locked into a win this week or don't need it, feel free to hold for Sunday. Otherwise drop now because after that they don't play again until Friday, their only game next week.
We've been saying Smith is a stream with hold/add upside for a couple weeks. After another big game, in just 24 minutes at that, let's just go ahead and officially upgrade the tag. The Aces play 6 games in round 1 of the playoffs in standard league schedules, making her an easy add over any fringe players you might he holding from PHX, GSV, MIN, or SEA.
