Those odds reflect what I think is possible, not what I think is likely. I think UConn has a reasonably possible path to the NC game through Duke, USC, and Iowa. These are all winnable games, but also losable games. The positive is that they are not likely to be rock fights like the last two. Also, there are no teams before the NC with insurmountable front courts for us.
If I try to run it for other teams, what I see is that Iowa has a possible path to the NC game and it's got a similar degree of difficulty or maybe a little harder. Stanford seems to me to have the roughest path to get there. USCw could get there, though they'd have to get past us or Duke and then Iowa. UConn and Iowa are likely to be difficult opponents for them.
Of course, I'm only talking about getting to the NC game, not winning it. I don't really think any team has a reasonable good possibility of beating SC.
