Couldn't pass this up...
Many times, players complain about "no calls" in practice. They say out of frustration, "In a game, that's a foul!" -- in an attempt to remind coaches to call fouls during drills or scrimmages. However, in a real game, players may not be able to finish because they aren't used to getting hacked -- or they aren't mentally tough enough to get through the hammering. Or, it's just plain immoral to let the fouling go.
So, take the angle of Adrian Dantley and his training tips, courtesy of a book from 1987, via 20 Second Timeout:
Playing underneath is tough, no question about it. You have to be willing to get fouled and take a beating. I prepare myself for this in the summer by playing with friends, working especially on my moves under the basket. We'll often play half-court for four or five baskets, and allow grabbing and holding when a player goes to the basket. Other times we'll decide to play the entire game without calling fouls. By playing like this, I'm able to concentrate on making my offensive move and following through with my shot even though I'm being pushed and shoved while I'm doing it. It often gets like that or even rougher when you play underneath in the NBA.
