A couple of things:
Joking reference to using Tuck's last name - gets to the practice/game names being short and easy to yell out - and the team had two possible 'Mo' players - Moriah and Morgan, but the second options for those two were definitely not equal - Tuck vs. Jefferson (Jeff was just not that appealing) - so Moriah got Mo, and Morgan was left as Tuck.
I get frustrated when watching Uconn on offense when open post players are missed, but sometimes the player with the ball is concentrating on something else and they just don't see them. The other issue is one of team philosophy - as Geno has mentioned a few times in post game - he has a team that shoots 50% so every turnover costs the team 1 - 1.5 points. Making a 50/50 pass into the paint costs the team on average 0.5-0.75 points. Early in the shot clock, that is not that good a trade off, so you run more offense in the hopes of getting the pass percentage up to 75/25 or better, whereas late in the shot clock maybe you go ahead and make the 50/50 pass.
Against teams that pack in to the paint, and most teams do that against Uconn, the player being 'open' posting up is not as open as it may look from the camera angle, since there are usually two other defenders who might get finger tips on a pass into the posting player.
Morgan is great, and her post moves are almost unguardable, but she is most effective in motion and threatening a defense from all over the court - the same could be said for Stewart. I have also liked what I am seeing from Lou in the past few games where she has also started posting up smaller defenders - she has been attacking the defense from more places on the court which can only help her whole game.
