As cynical as I've been, the PECOTA number seems wacky.
I think when it comes to W-L projections the best place to look is Vegas, which has us at an over-under of 84.5, which seems eminently reasonable.
(And before anyone jumps in with an explanation of how Vegas odds-setting works, that the intention is to have equal money bet on both sides, I know that. They move the number if there's heavy betting on one side.)
