Team chemistry is one of the most important characteristics for a team.
A squad can have a star-studded lineup with elite players, but without any connection they can flounder easily.
The shortened training camp had an impact on almost every team. Less time for practice means that it's more difficult to iron out kinks and edges for the regular season, especially if a team has a bunch of new players.
Probably the two teams least affected by the shortened training camps are the Oklahoma City Thunder and the Miami Heat. They pretty much have the same teams going into this season, and are both hungry and ready to play after disappointing playoff exits.
The next six teams, on the other hand, would've loved to have a few extra weeks to sharpen their skills.
