Here is a really nice RPI look at the teams in the Bracketbuster. It is even divided into home and away teams. Found someone referencing it on the OU board. It hasn't been updated for todays games so the Zips will likely rise a little, but right now the Zips have around a 72 RPI. The home teams in that range that we would be likely to play right now include
48 Iona
53 Oral Roberts
54 Missouri St.
60 Davidson
66 New Mexico St.
69 South Dakota St.
85 North Dakota St.
88 Wisconsin-Milwaukee
I'd actually be happy with any of these. OU, Can't, Cleveland St. and VCU are also in the RPI range but we won't get them since we played them this year. Butler's RPI right now is 112 but it would still be cool to draw them.
