OK, I'll give it a go. Sorry, it's long.
[Here is the tl/dr version: Duke didn't drop after going 1-3 because all of the teams immediately below them also **** the bed]
We have to agree on two things for it to make any sense:
- The Top 5 have been pretty stable for the last few weeks, forming their own tier: Baylor, Kansas, Gonzaga, SDSU, Dayton (in any order).
- To drop Duke from #6, you have to move someone else up to #6.
One of the things that has always bothered me about the NET is that we don't actually know what a given team's "NET" is! They don't publish the NET score/rating/whatever you want to call it, they just sort the teams 1-353 and put out the list. I don't know why they do this; perhaps they figure some math nerd will back into their formula if they publish the ratings? Most major computer rankings publish the number that their rankings are based on - for KenPom it's Adjusted Efficiency Margin, for example. With NET, we just get the rankings - no number. So it's very possible - I would even say likely - that Duke's "rating" actually fell, but the teams from #7-#10 weren't doing anything to stake a claim for #6. I believe I asked you after Duke lost to Wake, "Who
should be #6?" It's not easy to answer that!
If we knew the NET ratings, I bet they'd form a bell curve like most other ratings systems - which usually means the teams at the very top and bottom are more "spread out" than the mediocre teams in the middle. I'll save that for maybe another post, fan2011 can either back me up or shoot it full of holes.
But it's important here.
This was the "2nd Five" the day before Duke lost to NC State:
6 - Duke 22-3
7 - Maryland 22-4
8 - Arizona 18-7
9 - West Virginia 19-7
10 - Louisville 21-5
It's conceivable with only 3 losses that Duke was nipping on the heels of the Top 5 and had a little distance between themselves and #7-#10.
Maybe you flip them with MD after the NC State loss, but you're not dropping them further. I already know how you feel about #8.
Then what - MD loses that Saturday, Duke wins, and you flip them back?
The day before Duke lost to Wake:
6 - Duke 23-4
7 - Arizona 19-8
8 - Florida St. 24-4
9 - Creighton 21-6
10 - Maryland 22-5
Hmm. You gonna put the Seminoles at #6? Maybe.
And finally, before Duke-UVA:
6 - Duke 23-5
7 - Florida St. 24-4
8 - Creighton 21-6
9 - Maryland 23-5
10 - Louisville 23-6
That same day, FSU lost to Clemson. Creighton got blown out by St. John's. Maryland got blown out by Michigan St.
The three teams right below Duke before they went 1-3?
Maryland went 1-2.
AZ went 1-3.
WV went 0-3.
And
that's why Duke didn't move down. Who else could be #6?
I suspect the gap between Duke and the Top 5 is wider than it was two weeks ago.
