UConn will be very good this year. Of that, I am certain. But Notre Dame should be right there as well. Notre Dame's bench players may sit behind All-Americans this season, we'll see.
You're right about UConn's conditioning. The vast majority of their players could play all 48 minutes if only cardiovascular conditioning was considered. But bench players enter big games for other reasons as well, such as fouls and injury. UConn's starters have been fairly immune to each recently, but that could change.
Collier played injured all season last year. Following the season she had hip surgery to fix a problem that had bothered her since high school. She is expected to be healthy for the start of this season:

I do not agree with some of your matchup conclusions. Some of them seem irrelevant. For example, you compare Butler to Nelson and Thompson. First, I don't see Butler starting or playing much vs. Notre Dame (unless she makes big strides this season). I also do not expect Nelson to play either, and if Thompson sees the floor, then the game is a blowout and thus the outcome is not in doubt. Hence I think the comparison is irrelevant. Would I compare Mychal Johson to Molly Bent or Tierney Lawlor? No, because none of them would play a significant role in a clash between ND and UConn. Usually, only starters see significant minutes.
Center: Huskies will start either Butler (doubtful) or Gabby vs. ND's Brianna Turner. I give ND the nod here.
PF: Huskies start Collier (probably) vs. Westbeld or Boley. UConn wins this one, but ND freshmen sometimes play pretty well in big games. Westbeld is steady but not in Collier's league. Boley may be in the same league as Collier, but she's younger and less experienced.
W: KLS will be matched up against Mabrey. That's a good matchup, and it may depend on which shooter is hotter on that day. Remember that Marina had a great game
@Uconn last season and there is no Mo Jeff to shut her down in the second half this season. Notre Dame also has Jackie Young, so she should be an excellent backup that should see meaningful minutes this season.
SG: Nurse vs. Arike. Interesting matchup. Kia was surprisingly good her freshman year and the summer following her freshman season, but she had a somewhat disappointing sophomore year. Arike was raw as a freshman and didn't pass well. On paper, UConn has the edge, especially when one considers defense. But Arike is a very dangerous offensive player because she is a slasher, and UConn has to prove that their interior defense won't suffer too much this season with the graduation of the big 3. UConn wins this one, but let's see the sophomore jump for Arike. If she can make decisions with the ball this season, she could be fantastic. Big if, of course. Young could also see minutes at the 2.
PG: Do you really think that Dangerfield will outplay Lindsay Allen this season? I mean anything is possible, but my money is on a very good senior PG over a freshman who may not even start. Do you remember Mo Jeff's freshman year? I think while your opinion may be common on the BY (although I think many would oppose it), most basketball observers would expect Lindsay to have a considerable edge.
My positional analysis shows a much closer matchup than yours. Seems to me it comes down to coaching and intangibles. It should be an exciting matchup!
