This has been posted elsewhere, but I think it's neat. They grade/rate all the pundits, based on both getting the teams right, and bonus points for having seed right or close (see below).

Lunardi is just above average overall. Others are better. FWIW, 4 of the top 5 have ISU as a #3. The other the link was broke.
This rubric awards 3 points for each team correctly picked, 3 points for each team correctly seeded, and 1 point for each team not seeded correctly but was plus or minus one seed line (to compensate for procedural moves the NCAA does to make the bracket). With 68 teams, a perfect score is 408. The variance section of the data table below lists the absolute deviation between each score and the mean for that particular year. Thus, a 10 point variance means that site's bracket scored 10 points higher than the average bracket that year.
