Correctable Error

[michblue]

Saw this play in a game recently with a 2 person crew.....

Home Team at the FT line for a free throw attempt...As thrower releases the attempt B1 enters early (delayed violation) and L on baseline indicates the delayed violation with proper mechanic signal. FT is missed...no whistle from either official....B1 rebounds..play goes the other end...B3 shoots...shot is rebounded by A2...play comes back the other way....A4 shoots the ball and makes their shot...as the ball goes through the net...T official stops play and confers with L official on baseline. Both agree that missed delayed violation call is a correctable error (failure to award a merited FT)....Crew brings the correct shooter back to the FT line with unoccupied lane spaces....allow the FT attempt...and the give the ball back to Team B for end line throw-in as that is the POI.

I say this is a correct enforcement. Am I wrong?
