They made the playoffs in 2005, but did not get back until 2009. They have the same people making personnel decisions. Assuming they improve, they may be back, but they also have a tougher schedule.
I also think it's very difficult to assume they'll improve. They're much more likely to be content with what they've got, but I hope they prove me wrong. Maybe 19 straight years w/o a playoff win will be what motivates them. Time will tell.
