Really? While I think they are definitely capable of hitting 70 again I just don't think things will fall in line to have them do so. I think my over / under breaking point with GS would be 66. Not sure which way I'd go.
Thunder got weaker and Spurs are potentially weaker (depends no how much you value Gasol, the continued aging of Parker/Ginobili, and the loss of Diaw). Who is going to beat them in the regular season? I could see them beating the record they set last year. Only way they don't is if they rest players towards the end of the season, which they very well might. That would be the only argument I would see for going under on 70. Anything 67 or lower, I would go over on for sure.
