I'd give about 5-7 points for a home field advantage, and maybe I'm overconfident, but the amount that both schools lose, compared to what UCONN adds - I'm of the opinion that UCONN will be better by more than SC. I actually could see Baylor being better than SC next year as well as possibly Notre Dame and Tennessee.
In other words, we lose KML and Stokes - roughly equal to what Welch and Ibiam gave SC. But bringing back Stewie, Tuck, Jefferson, and Nurse as well as the quartet of Newbies (3 frosh + Butler) is far substantial to what SC adds in that PG from Canada. And against a team like SC, having Butler will be absolutely huge. Not saying she's as good as Coates or Ibiam, but against a really big team like SC, she will be invaluable.
For the record I was one of the UCONN fans that said we'd beat you guys by 20 this year. SC just didn't have the horses to hang with UCONN in my opinion. A really good team and in a universe where there was no UCONN, you'd have been in the NC game vs. ND. Next year you will have 3 legit players who could be AA's - Mitchell, Wilson and Coates. Problem is UCONN has 4, and they bring in the 2 best freshmen in the nation in Samuelson and Collier. And that's why I think the gap between UCONN and SC will be even larger next year... But hey, that's why they play the game.
