A couple of things to consider:
1. Entering the season UCONN has more question marks than they had last year, but so does every other team in America. Almost every team has question marks entering each season. Even Notre Dame still has uncertainty regarding Turner's impact and Mabrey's ability against smaller quick guards at the PG spot.
2. Even if the depth isn't there, UCONN has more talent than anyone else in the nation. Three number one recruits and 3 others who were top 6 recruits. No one else comes close to matching how top heavy the Huskies are.
3. Geno rarely goes more than 7 deep. If you have Dangerfield, Collier, KLS, Walker and Williams as likely rotation players..that leaves 2 spots for ONO, Camara, Gordon, and Coombs. Chances are 2 of those players will step up. Last year was more of an anomaly because you had so many freshmen plus Camara who had injury issues and was in her first year of eligibility at Connecticut. This year all of those players are back and know what expectations are and have a more realistic opportunity to make an impact.
4. UCONN players regularly make strides as a sophomores or juniors, especially when a rotation spot has opened up due to graduation. We saw it with Dangerfield last year, Tuck in 2015, Jefferson in 2014, etc. It's very rare that a UCONN player who was expected to step up and seize their role as a sophomore or junior hasn't been able to do so. This year it's Megan Walker who has the chance to make her mark. Coombs, Camara and Gordon also have an opportunity to step up as role players.
5. Having unknowns at certain positions usually bodes better than having too many good players competing for PT. Most years UCONN graduates a couple of talented players and it allows other players to step up and make their impact. Players seize the opportunity. Contrary to that, when almost everyone returns from a top squad and you add in another mega talent, the results usually aren't that great. 2018 UCONN wasn't better than 2017 UCONN despite returning almost everyone and bringing in Stevens and Walker. Same in 2001 when they returned everyone and added DT...that team just wasn't as good as the 2000 squad. We've seen it at other programs too (ex. Baylor in 2013, Notre Dame in 2017, Maryland in 2007, Tennessee in 1999). This year programs like Baylor, Notre Dame, and Texas will have to find minutes for a lot of top talent. Not a bad problem to have, but I wouldn't be surprised if the chemistry isn't as strong as a result from it.
6. Last but not least, UCONN has Geno coaching and he's lost just 3 games in the last 5 years. This team is immensely talented and I'll be quite surprised if UCONN drops more than 2-3 games all year.
