Orlando has built a really good team. You could even see it last year. The raw talent and potential on their squad. Especially Franz Wagner and Banchero. Very solid players.
Yeah, their bench is really deep too. Cole Anthony is a really solid backup PG (I've always been monitoring him because he was taken one pick after Nesmith). Isaac is obviously still a great defensive player when healthy. Mo Wagner has been great for them, which is something maybe casual fans don't really know. Then they also have Ingles who is slow and old but obviously brings experience, ballhandling, and shooting. Anthony Black is raw, but he was the sixth overall pick in the draft (I believe it was the Bulls pick from the Vucevic trade, thanks a lot Chicago).
Tatum and Brown can't simply do whatever they want due to the Magic's length and overall defensive depth. Therefore, when Porzingis went out it was pretty much game over. The offense became last year's offense. Even when they got steals, the Magic transition D was good enough to recover or create those awkward missed layups.
