Play 1: Secondary defender, any official can and should bring info. Grounded secondary.

Play 2: Play on, dribbler puts himself in path of defender who is running down, contact is marginal IMO.

Play 3: Would prefer play on given the pass goes to wide open 3 point shooter. This is where a rulebook foul isn't wrong but there is a better option for the game.

Play 4: If called has to come much sooner. Marginal IMO, offensive player is super close to LDB. Also where the hell is Slot going??

Play 5: Obvious illegal screen, not a fan of the blocking foul signal first. Use that at the table. Not sure what the question/learning point is here, it's an obvious foul.

Play 6: Yes whistle is too late. Either hit earlier and chance giving an and-1 or lay off entirely.

Play 7: Clock should be at 21 or 20 but not a huge miss.

Play 8: Lead. Lead should be more aggressive here and start going to take it.
