3-whistle: Throw-in below FT line extended

[zm1283]

How do you guys handle throw-ins below the FT line extended on the sideline when working with three officials? I know the NCAA-M mechanic is for the Lead to bounce the ball to the thrower, with the Trail counting and chopping the clock. We used to have the Lead bounce and count/chop, but now our association says that the state governing body wants us to have the Trail bounce the ball to the thrower (No matter how far into the corner he is) and then count/chop himself.
