They are 1000% better than last season. They don't have the ridiculous lapses in concentration and breakdowns in offensive play (Washington Wizards style). Kemba Walker is running them very well. He makes good decisions on shots, passes and pace. Byron Mullens is another big reason. The guy is growing up very quickly and will be a bigtime scorer in the league in a season or two. He has range and good touch inside. They have great interior D, intimidation factor is huge with Biyombo in there. Ben Gordon has chipped in - that's a nice signing. Kidd-Gilchrist seems to do a lot of things well, he will be a great player. Sessions is playing out of his skin as well. Probably the best backup PG in the league. They are also doing an okay job defending the three as well. Gerald Henderson is injured as well, and he's a pretty decent scorer, so they aren't going too badly at all.
Their schedule has been fair - not easy, not overly hard.
Bottom line, they are a lot more controlled. Whether it's Dunlap, Walker's maturity or a combination of both is up for discussion.
