So you're saying that -20.5 or -21.5 is a lot then like the betting lines now? That's only 1/2 a 3 pointer away from -20.
Now that their top scorer Kiyomi McMiller is ruled out, then of course it's possibility low now.
However, Jan really hasn't proven she wants to pulverize her opponent this year. Better to get others experience than to smash them with starters. If the subs also crush it, then so be it. Since it's also Vivian Stringer's territory, I don't see Jan wanting it to look like overkill. I may be wrong, but it just seems to Jan's early coaching style.
