Everybody seems in 100% agreement that UConn looked tired today. I was at the game, in the lower level about 30 feet from one of the baskets. I did not think that fatigue had a major impact on how UConn played.
Yes, there were small signs. I attribute Aaliyah's near misses to fatigue, but (as usual) she hustled more than almost anybody, so that may account for it. I did see one play where Caroline retreated on defense holding one of her hips. That can be a sign of fatigue, but in her case it can also be a sign that someone tweaked her in a spot that is still recovering from summer surgery.
I think that the Boneyard consensus about fatigue being a major factor reflects group-think. Some people seem to think that if starters play 35+ minutes 36 hours after getting off a plane from Omaha at 3:30 AM, they must be fatigued, and the fatigue must account for every missed layup or missed defensive assignment. I think that those mistakes have been present in every game against good opposition, so it's too facile to blame them on fatigue in this case.
UConn lost the second quarter by 3 points, then won the third quarter by 3 points and the 4th quarter by 6 points. The fourth quarter was UConn's best shooting quarter (61% after 50%, 31%, and 42% in the first three quarters). A fatigued team would be expected to perform worse in the last quarter of the game. I just didn't see that today.
