Re: pick and roll
I'll go first.
I have been taught this tactic at my first basketball camp and it was basic with not as much details because we were youngsters.
to me it was me as the screener stands with his arms protecting himself, sealing the ball handler's defender, then pinning that defender and sealing him off as I either ran to the corner for the open jumper or roll to the basket for a layup.
Not much details as I said but I practiced it with my partner and felt I became a decent pop jump shot man.
