Heat vibes, Alpha Sixers, Doncic domination? Top storylines for NBA preseason

The Miami Heat will head to Quebec City, Canada, to face the Toronto Raptors Saturday, Oct. 3. Both teams have been revamped, with Miami pulling off the blockbuster to land star forward Giannis Antetokounmpo , while Toronto reunited with Kawhi Leonard .

Those are just two of the teams to have undergone massive changes, and they're not even the ones that had the most seismic offseason; the Philadelphia 76ers went all-in on their championship window and added LeBron James and Jaylen Brown to Joel Embiid, Tyrese Maxey and VJ Edgecombe.
