The NBA isn't a climate that stays the same way for a long time. Thanks to savvy general managers and the draft lottery process, it's possible to go from zeros to heroes in the space of a season.
That's exactly what the Boston Celtics did when they won the NBA title back in 2008. They went from the bottom team in the Eastern Conference in 2007 to the champions of the world in 2008 - that's some improvement.
The Cavaliers are another great example. When LeBron James left to take his talents to South Beach - to steal a phrase - the Cavs went from first in the east to 15th the very next season. They remained out of the playoffs for the four years he was gone, but two years after he came back, they became NBA champions for the first time ever.

Will there be some dramatic turnarounds next season? Here are three early predictions.
Of course, the Pacers finished seventh last season and have the perennial all-star Paul George in their ranks. It's fair to say they are quite a good team from the get-go.
But, they've made themselves a lot better with some smart post-season plays. After trading for Jeff Teague, the Pacers swapped the defensive-minded George Hill for a more adventurous alternative in the former Atlanta Hawks guard.
Indiana have long been criticised as a team far too conservative, but changing men at the one spot gives the side a whole different outlook. Trading for Thaddeus Young gives PG-13 a talented frontcourt partner to bounce of off and securing Al Jefferson in free agency brings a potential double-double presence at the four or five spot.
All of a sudden, the Indiana starting five - when you factor in Monta Ellis as well - is pretty damn attractive. They can be expected to rub shoulders with Boston and Toronto as a top four seed next year.
New York Knicks
This one is pretty obvious, isn't it?
Carmelo Anthony and Kristaps Porzingis were very talented building blocks on their own, but their supporting cast was holding them back.
Phil Jackson took action this summer and finally gave Melo the kind of teammates he craved. Derrick Rose was traded to the Big Apple and Joakim Noah, like Rose, also departed Chicago, but via free agency.
Brandon Jennings is another impressive get, but the Knicks have to be worried about the health of all of their acquisitions. They certainly represent gambles, but they look good to surpass 32 wins next term and flirt with the final playoff berth in the east.
They've lost Kobe Bryant and they only managed 17 wins last season; things cannot be looking good for the Purple and Gold, right?
Wrong. Luke Walton has returned to the Staples Center after winning two titles during his career as a player, and he's now the hottest young coach in the NBA.
Many Lakers fans believe he will bring with him the floor-spacing offence that he helped coach with the Golden State Warriors, and that would seemingly be a perfect fit for the likes of D'Angelo Russell, Jordan Clarkson, Lou Williams and Brandon Ingram.
Chuck in Julius Randle and Larry Nance Jr., and it's evident the Lakers are on the brink of something decent. The additions of Jose Calderon, Timofey Mozgov and, particularly, Luol Deng are certain upgrades on what they had last season.
The Lakers only won 17 games last season and while the playoffs will be out of reach next term, somewhere between 25 and 30 wins isn't out of the question.
