Why isn't throw in spot after a "T" POI...?

[Dixon21]

After a technical why doesn't the throw in spot just go back to where it normally would have prior to the technical

I saw this "cost" a team in a game I was officiating.....

3 seconds left

Team A 60
Team B 61

Neither team in bonus

Team A gets fouled under the basket they are trying to score at. The foul is not a shooting foul and Team A will not be shooting free throws. The designated throw in spot is outside the lane under the basket they are trying to score at.

Prior to the throw in a technical foul is assessed to Team B.

Team A misses both free throws (but thats not the point)

Now Team A has to take the ball out at half court instead of under the basket where the originally would have. Team A ends up having to launch a desparation shot from much further away than they potentially would have had they been able to run in an bounds play from the original throw in spot under the basket they were trying to score at.

In my opinion, they were put at a disadvantage from the new throw in spot. Being awarded free throws is not the issue here and whether they make them or not doesn't matter.

Why are we still doing this?
