Question about foul during try

[Nevadaref]

You are correct.

This play ruling is for a FT, not a FG, but the concept is the same.

6.7 SITUATION B: After A1 starts the free-throwing motion, A2 commits a foul
by pushing B1 along the lane. RULING: If the foul occurred after the ball was in
flight, the point counts if the throw was successful and no substitute throw is
awarded if not successful. If A1 had not released the free-throw attempt before
A2 fouled B1, the ball became dead when the team-control foul occurred and A1
is permitted an unhindered free throw. The foul by A2 results in the ball being
awarded to Team B at the out-of-bounds spot nearest to where A2 fouled B1,
unless the free-throw attempt by A1 is successful in which case B will throw-in
from out of bounds anywhere along the end line where the free throw was scored.
