Yes I think they'll show up. I don't see any reason why they wouldn't. They played very well ever since that game in Utah on Jan 28th. Lost that game by only 3 and really played well in that one if you watched it. They clearly deserved to win. Preceding that game was a 2 hour team meeting with coach Keith Smart. They covered the game, the team responded.
Following that they split with GS, and in my mind outplayed GS in both games. Beat portland, beat NO (covered both), and just covered in Minny only losing by 2 (after minny beat houston convincingly). Moreover, Sac is fully healthy now and don't have the injury bug they had earlier in the season

They don't play the following day and only have 1 game to play in the next 4 days, and that one is at home to Phx. I don't see why Sac wouldn't show up for this one.
