It's not that simple Sano. If you take Love and Irving out, that gives you about 35-40 more shots to distribute to other players. While they aren't as individually talented as those 2, role players can usually play better with better rhythm (easy to play better when you know you're getting shots) and when you have LeBron, he can generate a lot of open shots for teammates to further enhance their value. That is not something debatable, LeBron has literally done this multiple times throughout his career. Also, with a LeBron heavy offense, his teams tend to focus more on defense, which hasn't been great the past two years, especially this year. The team he took to the finals without Love and Irving hobbled was pretty great defensively.

I don't think LeBron without Irving and Love makes the finals in the east, but it's debatable. And that's pretty impressive.
