If Detroit could get lucky with a trade or two, maybe they could squeeze in to the very bottom of the playoffs. Not right now, though. Kind of see them battling around with the Pacers, in that ~34 - 36 win space, not *quite* good enough to make it in but not bad enough to get a difference-making draft pick.
EDIT: Next year's likely playoff teams:
Miami
Boston
Orlando
Chicago (really like the Boozer signing)
Atlanta
Milwaukee (don't like all of their moves this summer, but mostly for cost; they'll be back in)
That's six teams. Charlotte could fall back, they still aren't a great team but they made the playoffs and Larry Brown makes them play hard. New York had a disappointing summer overall, but they've still improved a lot and I think has a good chance to earn the #7 seed. Toronto was basically a .500 club last year, but missed out. Let me go on record as saying I'm not sure how much worse off they'll be without Bosh. Philly could get better, quickly, if Evan Turner is as good as advertised. Indiana's not great, but a turnaround season from Danny Granger and a little health could get them up to #8.
Even Washington should be a lot better with John Wall, and MAYBE Arenas can give them something positive.
COULD Detroit emerge over that mass of .350 - .500 ballclubs? MAYBE - but seems like it's usually teams that get infused with new talent (like Turner, or Wall) that surprise. Detroit had injury issues last year, yes, but still - they won fewer than one-third of their games and haven't really added anyone to the roster.
