Been away for a few days...too much work.
Looks like I missed a good one!
My opinion...no T's. Definitely not on just one player.
I've got two possible solutions
1. When ref is ready to administer FT, there better be no players in the lane. I tell them to find a spot. If they had a time to get to a spot and are still in the lane when I'm ready to bounce, it's a delay of game warning.
2. Instead of a delay warning...tell them to find a spot.."I'm bouncing the ball to the shooter in 3 seconds. If you're in the lane when the ball gets to him, it'll be a violation." Bounce it on 3. Call the violation. They had the chance to find a spot.
