When you piss away 1/5th of the season, you have to change priorities. Right now the priority is to pass the Knicks and play as well as they can. If they can get the 6 seed they'd be most likely facing Chicago, Orlando, or Atlanta. All teams the Sixers could beat in a five game series. No matter what their seed is, whoever their opponent is will get a run for their money. They're making incremental improvements defensively, protect the ball, and play well at home. Those are very nice skills to have, especially when your team lacks a star.
Just making the playoffs is a huge step forward.
