Lots of angry Sixers fans following me here. Unreal. I think they know I’m right.

That’s correct. When you’re a win-now team you operate above the cap (or more likely above the first apron). You resign your existing players using Bird Rights and you trade away expiring contracts for longer contracts to add more talent.

The only way to be under the cap is to have a team of scrubs and guys still on rookie contracts or veteran minimum. No team not looking to tank and rebuild goes under the cap unless they have a prior arrangement (like Anthony Davis joining the Lakers).
