They're 1 behind in Massey/RPI. They're another 3 loss team with their worst loss being DePaul. They would have quality wins over top 30 RPI Maryland (2x), Iowa, Duke, Indiana, Ohio State and Michigan 2x. My guess is they get the nod over UCONN if that pans out, but my guess is they drop another game.
Funny thing is, Northwestern should probably already have a #2 seed -- and so should Maryland since the two have almost identical records.
Northwestern will almost certainly be the #1 seed in the Big Ten Tourney when it goes to the third tie-breaker. So Maryland will probably have to beat Iowa and Northwestern to win the title, and they lost to both of these teams on the road earlier in the season -- to Northwester by a whopping 23 points. (Of course they beat both of these teams at home, so who knows. And you can't rule Indiana out.)
Both Maryland and Northwestern split their series with Iowa. Maryland lost to NC State and South Carolina by 7 and 10 points respectively. Northwestern lost to DePaul by 2 points. Both teams beat Indiana for their only other Top 25 win. In the convoluted way of figuring these things, Northwestern actually has the best win of the two teams, because Maryland is higher rated.
Arguably, Maryland is only higher rated because they started off as #4 in the pre-season poll while Northwestern was not even among the 18 teams in the "also receiving votes" category.
Best case for UConn might be to have Iowa beat Maryland in the Big Ten semis and then beat Northwestern for the conference championship, since that would not bring a 5-loss Iowa team up to a #1 seed. (Unless of course they were really looking to screw the Huskies.
There's also an outside chance that Maryland loses to Minnesota on Sunday.
