This was my thought exactly. However, we say that every year. How will we replace Maya? How will we replace Kelly? Now, how will we replace Stef and Bria? The short answer is you can't. No two players are exactly alike and Geno is a master of creating offenses and defenses that highlight the team strengths and mask their weaknesses.
Next year we will be a bit thin on size (lose Stef and none of the newbies are over 6'1") and lose 2 leaders. There's no 5 that has ever played at UCONN who was as complete a player as Stef, and as adept at running the entire offense through her. So next year, Geno won't run motion offense around the center at the top of the key making decisions on how the offense operates. Defensively, and on the boards, I believe Kiah was actually better than Stef. This is not to take anything away from Stef, but Kiah, especially in the 2nd half of the year, became a complete monster on defense, and was a rebounding machine. Her athleticism is a matchup nightmare for slower centers, and if she can turn her defensive confidence into offensive production, watch out.
Bria had heart and guts and was a tremendous leader and an even better person. But from a hoops perspective, I agree her numbers are easier to replace. If Saniya and Brianna can't step up, I guarantee you Kia Nurse, or a healthy Gabby Williams will be willing and able to step right up.
Totally agree with what Doggy said above as well. Losing great players doesn't necessarily mean the wheels will fall off. It does mean that the offensive and defensive structure may well change substantially, and we will certainly see a new and different "look" next year. People seem to believe that the teams who will most likely challenge UCONN for a NC next year are South Carolina, Notre Dame and Tennessee.
Frankly, if you look at the beatdown UCONN gave ND this season, I believe UCONN would be even more dominant against those teams next season. ND because they lost more than UCONN (Braker, Aconwa, McBride) and don't add as much in their respective freshman classes.
South Carolina because IMHO they were way over rated and even tho they landed Wilson and White, their class is 3rd in composite rankings behind UCLA and UCONN. Oh, and not a single player on their starting 5 is better than their counterpart at UCONN (and that goes for Coates vs. Stokes).
Tennessee because there is nothing we've seen to indicate that they run any sort of organized offense, and no matter who they have on their team, it's unlikely they'd score over 50, (and I'd bet big $ they'd never score over 60) against UCONN in any game.
And in spite of the HS AA's on Tenn's roster, their best players are far inferior to UCONN's best players (Jefferson vs. Massengale/Carter, KML vs. Burdick and Stewie vs. Graves). Frankly I think Stokes is a wash vs. Harrison even tho Izzy has shown far superior offensive skills, and it's likely if Massengale comes back, Carter slides over to the 2 spot, and frankly, I'd call that match up a wash against Nurse or a healthy Williams.
