Not disagreeing with anything here regarding Vondrak and your last statement but someone "good" is likely going to be benched. Bigbee has regressed for whatever reason over the past year so she may be one and Vondrak may be another, especially if CJL goes to a 5-1 with everyone healthy and a tighter rotation. If she does go to a 5-1, my guess is the benched setter will be Horner if Harris isn't moved to a DS instead.
I would guess if we go to a 5-1, Harris will be the 1.
