sub for a sub
 

Is it legal for a substitute to be substituted for during the same dead ball period? example: A2 is waiting at the table to sub for A1. At the next dead ball opportunity, A2 enters the game for A1. B2 also subs in for B1. Coach A sees this and does not like the matchup between A2 and B2 and sends A3 to the table for A2. Is this legal? Please cite rules to support your answer.

A3 can enter the game.

A1 cannot re-enter until time has lapsed from the clock.

This is legal because there is NOT a rule which prohibits it. :D

The only way that A3 could be denied entry in this situation is if the coach took took long to make his decision and the ball was about to be put into play. In that case, the rule says that the beckoning signal should be withheld. (3-3-2)

There has to be a cutoff point so that the substitution process doesn't take forever.

That is what I thought. Since there is no rule against it, it must be legal.

There is an NBA rule which requires a player to remain in the game for one tick of the clock after entering. However, neither the NFHS nor the NCAA have this provision.

Unfortunately, the know-it-alls who watch the NBA will insist that the same must be true for HS games because that is what they saw on TV. :(

What about 3-3-Art. 4?
A player who has been replaced, or directed to leave the game shall not re-enter before the next opportunity to substitute after the clock has been started properly following his/her replacement.

So what I get out of this is you can't substitute for someone who has already been substituted out. You can however put a different player in.

So if A2 goes in for A1 then A1 has to wait until next opportunity ...however A2 can be replaced by A3 but not A1

OPPS...just saw Bktballref's answer...same thing.

That is it exactly.:D
