What'cha got on this?

If the basket misses, it only matters in the first scenario, with the coach being of the defensive team. In that case, the shooter gets three shots instead of two.

Since the shot wasn't taken, technically, in the 2nd scenario, it doesn't matter. The "shooter's" team still gets two free throws for the technical foul. The player technical in the 2nd scenario would simply be intentional, IMO.

Also, another difference in the two scenarios: offensive coach means it's an intentional technical (or flagrant technical if you desire), because the ball is dead. Defensive coach means it's a personal foul, which means the fouled player has to take the FTs (but means he will either get the 3 points or an additional FT). The inbounds spot is also affected.
