Every once in awhile this comes up, with comparisons to supporting casts. Taurasi, Moore and Stewart all had talented supporting casts, to emphatically insist that one supporting cast was better or worst than another only reveals the bias of the advocate. They were all talented; it's beyond the capabilities of any Boneyarder to demonstrate which was most or least talented aside from "because I say so."
However, there are a couple things we can decisively determine. Taurasi won a championship with decisively the least experienced talent. Maybe the talent of Strother, et al was greater or lesser than others ... once again, that cannot be objectively determined ... but they were undeniably the least experienced squad to win a UConn championship and they did so mainly because Taurasi led that team to overcome their inexperience. Whether Moore's teammates her senior year were a more talented bunch or not, which cannot be concluded outside of a biased "I say so," is beside the point. They were her team to lead and, if anything, a little more experienced than Taurasi's crew her junior year, and they could not get it done.
Moore scored a bunch (35 points?) in the last game she lost ... and I felt that was the problem. She did not know how to involve her team and make them better to the extent that Taurasi could. I'm not saying that Moore is bad at that, just that she could not do so like Taurasi. With Stewart we will never know. She always played with more experienced talent. I don't think she could do what Taurasi did with an inexperienced crew, but we will never know. However, Stewart did duplicate Taurasi's ability to lead an underdog to the championship ... and as a mere freshman. Moore only won championships while playing for teams that were heavy favorites. Granted, she was a big reason why they were heavy favorites, yet the same can be said for Taurasi and Stewart on their impressive teams. Only Taurasi and Stewart led teams that were not heavy favorites. In Stewart's case she was the key player in beating a team that already beat us three times that year.
For me, how one can lead a team to victory is the most important criterion for greatness. The greater the obstacles faced the greater the achievement. Taurasi overcame the greatest obstacles (though, in fairness, Stewart did not have the chance to overcome the inexperienced teammates obstacle), Stewart overcame the second greatest obstacle. For that reason I'd have to rank them Taurasi, Stewart and Moore.
Nice post, but just a note of caution - we all have this impression that 2003 was Taurasi and a bunch of callow freshman - but the starters on that team were:
Taurasi - junior 37 games
Moore - red shirt sophomore 38 games
Conlon - junior 29 games
M Valley - junior 18 games
Battle - red shirt sophomore 13 games
Strother - freshman 38 games
Wolfe - freshman 10 games
Turner - freshman 7 games
So there were 55 games started by freshman - Ann averaged 31.5 minutes a game, Turner 20.8, and Crockett 15.9 and Nicole was injured in the 10th game and didn't return that season (25.8 minutes in those ten)
On Maya's senior team:
Maya - senior 38 games
Hayes - junior 38 games
Faris - sophomore 38 games
Hartley - freshman 36 games
Dolson - freshman 34 games
Dixon - senior 4 games
Buck - red shirt sophomore 1 game
Walker - freshman 1 game
So there were 71 games started by freshman - Hartley averaged 31.8 minutes a game, Dolson 24.2, and other freshman 11.7 with Walker leaving after 17 games (18.8 in those games)
You can argue relative talent but minutes played by freshman for both of those teams were basically identical, the number of freshman starts tilts heavily to Maya's team, and in terms of ranking and reputation coming out of HS Strother and Turner were more highly regarded than Hartley and Dolson, and the two that did not finish the year also tilted toward Wolfe I think but they sort of cancel each other out. Willnett was a more effective contributor than Engeln and Johnson the other two freshman Maya's senior year as her minutes suggest.
The rest of the team experience is pretty well balanced - the sophomores on Taurus's team were both in their third year in the system so growth-wise close to juniors.
It is often argued that centers and PGs take longer to develop in college than other positions and I think while Stef was great, relying on a freshman center and a freshman PG in the NCAAs is harder than relying on a freshman guard and forwards and Stef really was all they had as a center by the NCAAs.
What Taurasi and that 2003 team was able to accomplish was magical, what Moore and that 2011 team was unable to accomplish was 'shattering' - they both had daunting tasks to lead teams relying for important contributions from freshman.
