Two separate issues. I don't necessarily think that Tennessee will be one of the top challengers to UConn's crown. Going into next season, South Carolina, Notre Dame, Baylor, Texas, Ohio State, Maryland and Louisville should all be ahead of the Lady Vols in the pecking order.
I'm sure that Dangerfield will fit in nicely into UConn's returning lineup, but I don't see her being as good as a freshman as Moriah Jefferson was at a senior. I also don't think that any of the returning players will be able to replace what they lost with Stewart and Tuck graduating to the WNBA. They still have talent, and they still have Geno at the helm, but there is a strong likelihood that they will look like the team right after Taurasi graduated; talented, but firmly in the middle of the pack.
That will all change once Azura Stevens suits up, so the opportunity is there for the top teams to claim their scalp once they are vulnerable.
I agree with your assessment of UConn, but I'm not that impress by Louisville or Texas. Both teams will be loaded, but only 5 can take the court at a time. Louisville should of at least made it to the 2nd weekend this previous NCAA Tournament. Texas will be talented, but like us some times they look terrible on offense and struggles to score. I also think people over react when it comes to Baylor. They've been loaded the last few seasons and what have they accomplish? It never fails, Kim Mulkey plays a very weak schedule during the non-conference and then goes into BIG 12 play undefeated and then walk through the BIG 12 with a few hiccups and gets sent home in the Elite 8. I'm telling you I do not see these 15 player rosters working out for Baylor, Louisville, Maryland, Ohio State or Texas. I just don't see the point of having a maximum amount each year. I think a roster of 12 is good. After last season, when it comes to the Tournament things can change drastically. It's all about match-ups. Maybe we will perform better since the target is not on our back and finally get to the Final Four. To me next season is wide open.
