Over at Wages of Wins, Erich Doerr has compiled and collated the projections of several advanced stats gurus (and, it looks like, Vegas oddsmakers).
The spreadsheet listing all the various projections can be accessed directly here. Averaging the 9 projections for the Hawks for the upcoming season gets 34 wins. The lowest projection is 28 wins, the highest projection is 39 wins.
All that assumes that I'm reading the spreadsheet properly.
In the interests of balance (and to keep everyone current with the small but lively Hawks blogosphere) let me pass along both that Drew has re-christened Hawks, Dawgs, and Jesus as Zaza's Playground and he has described the best-case scenario for 2008-09 season.
