You're highly underrating this 3 game stretch.  WSU and Zona are way, way better than Arkansas.   2 wins in this stretch would have me over the moon.
I think, for this team, and not the selection committee, one win is a success.  Likely against Auburn if it happens.   I expect a blowout against Zona, unless they catch them flat as they were earlier in the year.  As Fishy mentioned, UCONN's got no answer for a couple of their guys.  WSU is an experienced club which I believe will paste us.   I would put the chance at three wins in the neighborhood of less than 1%. 
Again, this assessment is just based on how they've played so far.  Perhaps the 12 days magically changes some things, but I'm just not very sure about that.   Generally:
- They'd have to play a full 40 minutes of top end effort (we've yet to see a complete half, never mind a full game imo).
- They'd have to stick with the offense and movement the entire game (I've seen stretches of less than 10 min per game so far).
- Larrier/Jalen/Vital would have to be ON, from the jump. 
- WSU and Zona would have to come out flat.
That's a lot to break right.
