Miami Heat - Risky, Floridian teams do struggle to get an audience, even when 1 of the best. Currently 1 of the better teams. Best player they have is LeBron James and are currently a squad that can win it all again.
LA Lakers - DAT HISTORY, more recently made the beast squad they had even more beast lol
Toronto Raptors - Dunno a hell of a lot about then. Only Canadian team in NBA.
Portland Trial Blazers - Dunno anything about them. Sorry lol
Dallas Mavs - They won it all for the first time a year back. I really like the home kit, but once again dont know that much
Pistons - In 00s they were THE team. A dynasty that really were hard to beat. Sadly, they now 1 of the leagues strugglers and are in a rebuilding seasons. I will say that Detroit are a very loyal fanbase, even to the weaker teams cause they have a knack for bouncing back to at least play-off contenders.
Don't get me wrong here, these 3 teams are most likely to win this season. Doesn't mean they will. For all I know, all 3 teams may go out first round of the play-offs. But more then likely either Oklahoma City Thunder, LA Lakers or Miami Heat will win/at least make the final.
You've picked a good mix of leveled teams though Shaz so you're not bandwagoning. Just watch them play home games once or twice and just see who you enjoy the most.
