6.4.1 SITUATION C: Following the jump between A1 and B1 to start the first quarter, the jump ball: (b) is touched simultaneously by A2 and B2 and it then goes out of bounds; (c) is simultaneously controlled by A2 and B2; In (b) and (c), A2 and B2 will jump in the center restraining circle regardless of where the ball went out or where the held ball occurred.(4-12-1; 4-28-1)
So, after over sixty posts in this thread, are we all agreed that these two specific situations (above) are the
only two specific situations where the rules designate jumpers, who cannot be replaced, or substituted for (unless injured, bleeding, disqualified)?
And that
in all other possible jump ball situations, jumpers may be replaced (a player already on the floor),
or substituted for (eligible substitutes, i.e., sit a tick, where appropriate, i.e., overtime jump ball).
