The two highest values drop to 0 -- and you have four starters with 0 previous minutes and the average drops dramatically.
Then try the next best metric -- players that played college basketball the previous season. Again, 4 from ND did not play the previous season, and a 5th didn't play 75% of the previous season, and the 6th barely played while recovering from being out the previous season -- and then missed the first half of the season being evaluated.
In short -- ND is the only team that had in effect zero returning players that played college basketball the prior season and 4 of 5 starters that had zero minutes playing for ND.
although one player was the issue
That shocking bastard
to why those teams were so much better. Those were the point guards on each of the 3 teams you list the minutes and each was the player with the most minutes. Then you bring up Oregon and I don't have to even look at the stats to know Sabrina had the most minutes on that very experienced team. Sniezek was only with her team 1 year while the other 3 were 4 year players on the same team. All the point guards were eligible to be drafted in the WNBA. They go: #1 Sabrina, #7 Harris, #16 Dangerfield. Sniezek not drafted, but she will parlay her Stanford/ND education to a fine future.
Add that the second experience player for the 4 teams you compare were drafted by the WNBA at #6 Herbert Harrigan, #8 Hebard, & #9 Megan Walker vs Destinee who still has a year left and probably won't go that high in next years draft, the quality of that experience matter as the glue to a team's success with the equally talented younger rosters (with the exception of the more experienced Duck team).
At one point, I suggested that UConn wasn't as far from a season like ND's if they had had similar experiences (player with most experience out for the season. 2nd most experienced player out for quite a few games early on, a senior to be leaving early, etc.).
One common response was "You can't compare those particular players being out due to the difference in talent level! Those aren't equal talent rankings!" (Ignoring the fact that I was using playing experience and position, not talent level in my comparison).
Auriemma typically doesn't go that deep most seasons anyway (typically going only 6-7 player deep until they get to the blowout stage), but last year they had a lot less experience in their backups than usual. They wouldn't have been able to make a 2001 type recovery (when they lost Abrosimova and Ralph, yet still stayed in the top 2 and made the Final Four) if they had a similar injury situation to that year.
For Notre Dame's players, many of those "previous minutes" came from other teams. I think if there was a way to take into account "previous days on team roster" then we would get a more faithful explanation for the woes of 2019-2020. For Notre Dame, Vaughn's and Gilbert's combined 556 previous minutes were darn near the only previous minutes played in a Notre Dame uniform on the entire roster (Cole and Benz contributing a scant bit otherwise). Meanwhile, aside from the freshmen, everyone in these tables for Connecticut and South Carolina had been on their respective rosters in 2018-2019, and although you don't show the players I think the same is true for everyone on Oregon besides Minyon Moore. That's at least one whole season of practicing, learning the coaching style, learning the plays, and developing chemistry that every player on those teams had that Notre Dame didn't - not even Sniezek and Walker who came from elsewhere.
Like you said, numbers don't paint the whole picture. If we consider how many minutes our players had logged in South Bend, it provides some more context to your numbers and helps explain the rag-tag nature of the team this past year.
also contributed.
The peer group integrated talented new players and let them grow in their roles. You always want to restock rather than rebuild. It wasn't surprising to me that the team played better when Mik returned from injury. Other symptoms of this were a large number of unforced turnovers (players in the wrong place) and desperate shots at the end of the time clock.
Other issues were the number of players who were coming back after missing most of the previous year and an imbalance of skills (nice way of saying we didn't rebound well).
I'd be interested to give values of 1-10 for each players ranking and 1 - 5 for minutes played and multiply them together. Teams with more talent in younger players, like us, should stand out.
