UConn and Purdue might separate themselves record-wise, but I think that will have more to do with conference strength than anything else.
The computers love Houston, and Vegas has Houston right there with UConn/Purdue. KU's been a different team with Furphy starting. Right behind UConn/Purdue per Torvik since then. Wins over AP #1, 4, 5, 10, 23 and 25. I think Marquette's right there with the best too, among a few others.
UConn/Purdue deserve to be ranked 1/2, but I don't see how either has shown to be clearly above the rest.
