The INBOUNDER has the most difficult job. Therefore, we must have a meaningful checklist which allows us to safely inbound the ball.
1) The INBOUNDER should not step out of bounds until the name or number of play has been called/signaled and the team is set. Moreover, do not stand on top of out of bounds line: move back 2 or 3 steps so defender cannot shield your view and/or deflect the pass.
2) Know that as soon as the ball touches your hand that the 5 count begins, not when you slap the ball;
3) Use your best passer to inbound the ball.
4) The INBOUNDER has a mental checklist that is prioritized by you.
5) Ask the official to count out loud. He may not do this but usually it will buy you extra time.
6) Whether you are taking the ball out on the sideline or baseline do not key your look, meaning stare at your first option. We suggest that the passer "look through the bottom of the net" as this gives broad vision from sideline to sideline so he/she can see all options.
7) With all SLOB/BLOB's the passer cannot move and must have a permanent pivot foot. Otherwise, coming out of a timeout it is important that the passer ask the official if he/she can move. Yes, we will remind him before he/she leaves the huddle whether movement is allowed.
8) Do not enter the ball directly under the basket as the backboard acts as another defender.
9) Pass fakes are a key buy and act as a decoy.
10) When the count is winding down the passer can either throw it off nearest defender or call a timeout, should you have another one. Additionally, give the inbounder permission to eat the ball. Yes, this is a violation but the advantage here is that your opponent cannot run off the turnover as you get to set your defense.
11) As a course of habit, the INBOUNDER should not initiate the play with a bounce pass. WHY? If the ball first hits out of bounds then it is a violation.
12) Practice, practice, practice. This means weaving in a 5 minute time block every other practice where each team has 5 possessions to not only enter the ball but also complete the exact play. Please keep the amount of makes and give them the % at end of competition. The players like this time block as there is meaningful competition and you get a winner and loser.
13) Most times the ball cannot be inbounded because the screeners don't sprint their picks, and the cutters leave too soon, and jog their cuts.
14) A fundamental teaching point here is that screeners and cutters must read their defender and not stare at the ball.
I am certain you have your own system and thoughts for inbounding the ball. The rehearsal of such a key situation can determine whether you win or lose a championship.
