That's at the very least.
Haws has a block at 12min. A missed shot at 10:43. More stats at 9:33 and 9:12. I'd bet he was in that whole time. Between that, Nixon is also in recording stats at 11:55 and 11:20.

Worthington has a stat at 6:48. So you'd have to squeeze in the possibility of all 5 playing basically between 9 and 7 minutes left. Probably even smaller time frame because those are just the first and last recorded stats by white players, not when they checked out and checked in. Would they really randomly put those 5 in for just a minute or so at that point? You'd think that would be memorable.

The perspective you looked from only looks at which black players are in at different points, but forgets to look at the clear instances when there was also a white player in, making it impossible for that period of time.

It's easier to first find when any white player was in, rather than trying to line up all 5 black players at once, because any white player automatically cancels out the possibility for however long he was in.
