Darko will be the scapegoat this year. Not Mayo. He's a rookie. I don't see why any rookies should be the "scapegoat".
Darko has gotten to the point where nothing is really expected of him. If Mayo does not come out of the block like gangbusters, and Mike Miller and Kevin Love have big seasons the atmosphere in Memphis could be poisoned. Mayo could try to justify his hype and start gunning. Young nuclei are fragile. See early 00's Clippers, Mid 90's Mavs, Core Bulls.
ihatetimthomas got it right with Philly and Andre Iguodala. He signed that huge contract this summer and has to live up to it or at least come close. It wouldn't be Mo Cheeks. If Brand isn't fitting in it'll be because "the team hasn't gotten used to having that low post weapon yet". But Iggy's been here, he's our leading scorer, got the big money, now has to produce like he earned that money.
