Whether this is better or not, Auriemma has consistently started experienced guards when he has them, even with better talent on the bench. Players like Sales, Ralph, Taurasi, Hartley came off the bench. Whether or not this is related Auriemma also has stated that he prefers to know what he is getting, having relatively mistake free playing, at the start. I presume that enables him to make more precise adjustments.
None of the guards who started over Sales, Ralph or Hartley had bona fides close to that of Muhl (though Doty might have been great if injury free).
I realize your comments were about minutes, but you responded to a comment about starts and I know you usually focus on mcbb, so I provided this background.
As for
@meyers7 comment, some may not have picked up that for Arnold to start at pg, both Muhl and Bueckers would have to be injured, and it’s doubtful that Arnold would start at any other position given UConn’s roster. So I heartily agree with him, if Arnold starts that is bad news for UConn.
