PhoSita did an excellent job of reviewing the stats through the first 20 games, highlighted several problem areas (shooting, lack of FTAs, and dud games), and concluded that having several young players shouldering a lot of responsibility is difficult. He also used the word linear somewhere in there.
It's also been pointed out that they tend to get up for difficult but not weaker teams, which is a sign of hangover. I'd speculate that a team this talented and coming off a great playoff run, with now so many guys failing to perform, is characteristic of a significant locker room issue. Not sure where that may be coming from though, since nearly all of these guys are first-class w/out a history of those issues.
