I wouldn't have "prolonged contact" in
VB, and I don't have a "catch" in basketball.
This is from NCAAW, but I'm (sort of) certain that NCAAM is the same:
Art. 7. A tap is a type of try for field goal whereby a player attempts to score
two or three points by directing a live ball into her team’s basket with her
han
d(s) or fingers without the ball coming to rest in her hand(s).
A.R. 123. With two-tenths of a second (.2) remaining on the game clock in
any period or extra period, Team A is awarded a throw-in at the division line.
A1 passes the ball to A2 who:
(1) Catches the ball with both hands while in the air and throws the ball into
her basket; or
(2) Does not catch the ball but taps it into the basket.
In both (1) and (2), the ball is in the air on the way to the basket when
the period-ending horn sounds.
RULING: (1) Illegal. When the game clock displays three-tenths
of a second (.3) or less and play is to be resumed by a throw-in
or a free throw, a player may not gain control of the ball and try
for goal. When this situation occurs, the official shall blow their
whistle and the period or extra period is over, unless an intentional
or disqualifying foul was committed on the play. Whether the try
for goal was successfully attempted before the expiration of time is
inconsequential.
(2) Legal. When the player does not possess (catch) the ball but taps
it into the basket before the period-ending horn sounds, the official
shall use replay equipment, videotape or television monitoring, when
available and located at courtside, to ascertain whether the tap (try)
was released before a reading of zeroes on the game clock.
